There is a growing concern about students’ attitudes toward mathematics in vocational education. However, not much is known regarding the factors that affect these attitudes. In this study, a new conceptual model is developed based on van Aalderen-Smeets and colleagues’ theoretical framework of teachers’ attitudes to explore the factors that affect students’ attitude toward mathematics in vocational education. The new conceptual model consists of five constructs of attitudes: perceived difficulty, perceived relevance, anxiety, enjoyment and students’ competence. This model would serve as a basis for future study in this field. The model is then tested on a sample of 215 vocational education students. These tests conclude that competence, enjoyment and perceived relevance significantly related to attitude and that competence was the most influential factor of attitude.

Lightweight geopolymer is a new innovation in concrete industry. It has an advantage because it could act as geopolymer as well as lightweight concrete. It is environmentally friendly since it is not produced with Portland cement which normally emit CO2 gas, a major contributor of greenhouse gases and global warming in the atmosphere. The material used in this experimental study are precursors, fine aggregates, alkaline activator solutions, superplasticizers, and foam. The precursors used were fly ash and kaolin, in which the percentage of kaolin were 0%, 5%, 10%, 15%, and 20% of the weight of fly ash. The concentration of NaOH at 12M and 14M. The results from the flow table test revealed that the optimum diameter of the mixture was 25.28 cm, which was found when the percentage of kaolin was 0% and the concentration of NaOH was 12M. The results of setting time showed that the fastest initial and final setting time of the mixture were 245 and 360 minutes respectively, also discovered when the percentage of kaolin was 0% and 12M NaOH. In addition, the optimum compressive strength of the mixture was 19.20 MPa, discovered when the density was 1481.12 kg/m3, percentage of kaolin was 0% and at 14M NaOH. Then, the microstructure analysis of the mixture showed that increasing the concentration of NaOH without adding kaolin produced a dense geopolymer matrix with very small pores, however, when kaolin is increasingly added to the mixture, it produced a less dense matrix with large pores. In conclusion, mixtures without kaolin resulted in lightweight geopolymer with better properties and characteristics.

k-Nearest neighbor is a popular classifier and has been applied in many fields. One problem with this classifier is the choice of k value. Different k values can have a large impact on the predictive accuracy of the algorithm, and picking a good value is generally unintuitive by looking at the data set. Because of the difficulty in selecting the k value, it is suggested to using variable k values instead of just one static k value. The numbers of nearest neighbors (k value) selected for different categories are adaptive to their sample size in the training set. There are many ways of choosing the k value, but a simple one is to run the algorithm many times with different k values and choose the one with the best performance. However, this method will take long time if we want to do experiment with a lot of k values. In relation to this problem, this paper will present the result of our experiment on what data properties affect the choice of k value. There are two interesting results from this experiment. The first is the experiment result showing the relationship between big data sets with more than 8000 instances (Mush, MGT, SS, Adu, and BM) and small best k values in 2-class data sets. And the second is where there is a relationship between data sets having numerical attribute type and small best k values in n-class data sets.

In this paper, we consider that all graphs are finite, simple and connected. Let G(V,E) be a graph of vertex set V and edge set E. By a edge local antimagic total labeling, we mean a bijection f:V(G)∪E(G)→{1,2,3,...,|V(G)|+|E(G)|} satisfying that for any two adjacent edges e_1 and e_2, w_t (e_1)≠w_t (e_2), where for e=uv∈G,w_t (e)=f(u)+f(v)+f(uv). Thus, any edge local antimagic total labeling induces a proper edge coloring of G if each edge e is assigned the color w_t (e). It is considered to be a super edge local antimagic total coloring, if the smallest labels appear in the vertices. The chromatic number of super edge local antimagic total, denoted by γ_leat (G), is the minimum number of colors taken over all colorings induced by super edge local antimagic total labelings of G. In this paper, we investigate the lower bound of super edge local antimagic total coloring of graphs and the existence the chromatic number of super edge local antimagic total labeling of ladder graph L_n, caterpillar graph C_(n,m), and graph coronations P_n⨀P_2 and C_n⨀P_2..

Liability or debt is an economic sacrifice that must be made by the company in the future due to previous actions or transactions. In accounting, it is defined as the liability of a business entity or company to a third party that is paid by submitting assets or services within a specified period of time as a result of past transactions. The economic sacrifice can take the form of surrendering money, other assets, services or doing certain jobs. Transaction actions can be in the form of receipt of money, goods or services, acknowledged a cost or loss. Obligations result in a bond that gives the creditor the right to claim company assets. Obligations can usually be determined in amount or easily estimated or expressed in units of money. Obligations are funding sources originating from creditors. In a company's balance sheet, the account is combined with the amount of liabilities plus capital or owner's investment.

Recently, the notion of the uniserial dimension of a module over a commutative ring that measures of how far the module deviates from being uniserial was introduced by Nazemian in 2014. In this article, we give some methods to determine the uniserial dimension of a finitely generated primary module over a principal ideal domain, especially using Python. It is well known that finitely generated primary modules over a principal ideal domain can be decomposed as a direct sum of finite cyclic submodules where the orders of the cyclic generators are called the elementary divisors of the module. We show that is depends on prime factorization of m and n.

Geographic addresses are essential in position-based routing algorithms in mobile ad hoc networks, i.e. a node that intends to send a packet to some target node, has to know the target's current position. A distributed location service is required to provide each node's position to the other network nodes. Grid Location Service (GLS) has been known as a promising location service approach. In this paper we present a new approach called TGrid and describe the performance of a novel multi-level Tree-walk grid location management protocol for large scale ad hoc networks. We provide a qualitative comparison of GLS and TGrid using statistical analysis beyond the results of the original paper and a theoretical framework. We present analytical results with respect to three main metrics: query cost, maintenance cost, and storage cost under two traffic patterns: uniform and localized traffic pattern. The proposed approach is evaluated through mathematical analysis, and the results indicate that our protocol scales 11well with increasing of node-count, node-density and node-speed. We show that the tree Main metrics, query cost, maintenance cost, and storage cost in TGRID grows only logarithmically in the total number of nodes in a uniformly randomly distributed network.

Research says 60% of visits to a doctors are for simple small-scale diseases, 80% of which can be cured at home using simple home remedies. These diseases mostly include common cold and cough, headache, abdominal pains, etc. They may be caused due to the changes in the weather, intake of improper diet, fatigue, etc. and can be cured without the intervention of a doctor. There are a number of chatbots which provide services for the healthcare domain. But the problem with these chatbots is that they only provide answers for general healthcare FAQs. That is, these systems are unable to provide a natural communication with the user just as a doctor can. Work is being carried out to enable the chatbots to communicate in a way similar to the communication carried out between two humans. That is, the user must experience the feel of communicating to a person and not to a bot. This makes the chatbot a virtual communicating friend of the user. This type of smart communication (usually used in healthcare counselling) can be achieved by inclusion of NLU, NLP and ML techniques in the conventional scripted chatbots. There are a number of domains wherein the smart chatbots provide their functionalities. This paper briefs about the chatbot system for the healthcare domain. Also, it specifies various NLU, NLG and ML techniques to be incorporated in the chatbot and the comparison of the same.

In the context of legislative and presidential elections, various identities are sung by political elites to win political battles. Since the colonial era, old, and new order up to the reformation order, the elite of the campus, bureaucracy, religion, and the party took advantage of their interests by displaying the colors of their respective identities. This condition has implications in the arena of battle, which has both constructive and destructive impacts on consciousness. Chronically, when the practice of the bureaucratic elite becomes a contradiction between the idea of collective identity and its actions, finally at the local level, it falls prey to removing the value of wisdom and continues to be in a discourse space that is never finished.

Many industrial power plants burn fossil fuels to get their energy while releasing flue gases to the atmosphere. Greenhouse gases are responsible for global warming and which causes severe environmental impacts. Carbon dioxide capture from the coal-fired power plant is important to maintain a better clean environment. The Post-combustion chemical absorption process is the most viable option to capture Carbon dioxide from industrial flue gases. The carbon dioxide capture model is developed and implemented in Aspen Plus process simulation software to calculate the required re-boiler energy demand. The required re-boiler energy demand is increasing when CO2 content of the flue gas is decreasing. The re-boiler energy is calculated as 3481, 3620, 3840 kJ/kg CO2 for the 85, 90 and 95% CO2 removal process for flue gases from EDF CHP power plant, Krakow, Poland.

The method used in this study was a survey method with a quantitative approach with a sample of 63 respondents using multiple linear regression analysis to get a better understanding of the effect of independent variables on the dependent variable. The results of this study indicate that: (1) financial literacy had no significant positive impact on investment decision making. (2) overconfidence had a significant positive effect on investment decision making. (3) regret aversion bias had no significant adverse impact on investment decision making. (4) risk tolerance has no significant positive effect on investment decision making. (5) Simultaneously financial literacy, over-evidence, regret aversion bias, and risk tolerance had a substantial impact on investment decision making.This result confirmed that most of young Surabaya investor was not rasional. Most young investors who may be more unstable in emotions, subsequent research was expected to be more varied. To reduced overconfidence it was better before making an investment decision investors do the right analysis, always update knowledge, update the latest news, and still had a trading plan so that it can reduce overconfidence. Investors should have high confidence, and be rational in making decisions, not just transacting shares due to herding which results in capital market instability.

Farmers throughout Iran are facing the more and tougher task of adapting to the consequences of climate change that embrace warming temperatures, exaggerated precipitation and storms, and new pest and illness challenges. Farmers should adapt their farming practices so as to become more resilient. Resilience is the ability of a person or system to absorb change whereas still maintaining basic structure and performance. Many organizations operating to extend resilience to climate change with local communities additionally acknowledge the importance of gender, however, the degree to that gender is really integrated with climate change projects is unclear. In the meantime, women are more vulnerable than men to counter climate change, and there has been no research on the extent to which women are resilience facing climate change. Also, male and female adaptation measures against climate change have not been compared. That is one of the most important researches for future policy-making and planning.

A teacher needs to compromise the abstract nature of fraction material in order for students to have a better understanding of the concept. The purpose of this research therefore was to find out the type of errors made by students when learning fractions and their achievement of reasoning ability through the Indonesian Realistic Mathematics Education (PMRI). The design of this research was quasi-experimental, involving two schools with one control and one experiment class in each school. One school is private, while the other is public, and classes from each were chosen as experiment and control classes. From these schools, the teaching and learning process using PMRI was only conducted in the experiment classes, while in the control classes, conventional teaching and learning was used. The learning process used concrete objects as the learning media, namely: paper, mortar, and fraction boards. Through the use of fraction board, students can find two simple fractions with similar values. There is a difference in the students' achievement of the mathematical reasoning ability between the implementation of the PMRI and conventional approaches. In general, the students found difficulty in understanding and stating a fraction based on the representation of a unit expressed by image/facts. The students often misinterpret the word "part" not as part of the whole, but as a specific unit based on the number of pieces available without being divided by the whole. The error of doing calculations was the most frequent mistake made by the students and is categorized as the common error category.

Nowadays, a lot of people using air transportation services, including people with disabilities. Government commit to give special treatment to people with disabilities, to provide them protection through the regulations that should have implement and obeyed by government, citizen, and airline companies. That regulations aiming to ensure equal rights and freedom of people with disabilities. Has the legal protection for people with disabilities been regulated in Constitution No. 1,2009 and the Montreal Convention, 1999? How are the cases of people with disabilities resolved due to Ridwan Sumantri and Dwi Ariyani? Those are the question of this study. The purpose of this paper is to describe the role of national and international regulations in providing legal protection for people with disabilities. The study is a normative study with secondary data and supported by primary data and analyzed descriptively through a qualitative approachment. Chapter 134 of Constitution No. 1, 2009 concerning Aviation is regulating people with disabilities, but the Montreal Convention of 1999 does not. Different judges applied the same legal basis for the two cases as the basis of the verdict, such as Constitution Number 1, 2009, whereas the implementation is different. The Ridwan Sumantri case applied Constitution Number 1, 2009 concerning Aviation, because the legal basis of the transportation agreement refers to chapter 134 of Constitution No. 1, 2009 regulates Disability. Based on that legal basis, the airline Lion Air responsible for paying fine along with apologies. But in the case of Dwi Aryani, the airline didn’t carry the verdicts, even though Dwi submitted a warning to the Etihad airline through ICAO (International Civil Aviation Organization) because the Etihad airline is subject to the Montreal 1999 international convention regulations which does not regulate disability.

The greatest challenge in fingerprint recognition is verifying distorted fingerprints. Distortion in fingerprints may arise from errors introduced while acquiring fingerprints, the nature of the fingerprints or from how there were deposited (in the case of latent fingerprints). In this paper, two convolutional neural networks were trained using different approaches. The first was trained in a regular pattern while the second was trained with an approach that minimizes errors that arise from verifying distorted fingerprints, and hence proposed for training models to be robust to distorted fingerprints. The trained models were evaluated on good and distorted data-sets. Results are modest and show better performance in the second model, compared to the first.

Immune responses during pregnancy are specifically regulated to allow fight against infections and prevent any damage to the growing fetus. HIV infections, a pro-inflammatory infection, present a challenge to the enhancement of pregnancy specific immuno-modulation of pro-inflammatory immunity. HIV Infection during pregnancy remains a health concern in regard to immune response and status. The immunological outcome of HIV-infected pregnant mothers and their effect on the health status and pregnancy outcome are areas of paramount importance in public health. In the current article, we review current data about the characteristic progesterone and immune responses in conjoint cases of HIV infection and pregnancy and present an immunological hypothesis to explain the findings. In conclusion HIV infection in pregnant women is associated with lower progesterone and increased cellular immunity compared to HIV-non-infected women. There is a clear indication that HIV infection may cause lower levels of progesterone among the HIV-infected pregnant women compared to the HIV-non- infected women. Most of the highlighted studies have indicated that HIV-infection during pregnancy is characterized by an elevation of both inflammatory and regulatory immune responses in response to both HIV infection and pregnancy concurrently. The reviewed studies have shown varied results regarding the lymphocyte counts during pregnancy and HIV infections. It, therefore, remains unclear how HIV infection would affect lymphocytes counts as pregnancy advances considering all arms of the immune response in a single study. Further researches are thus required to address the mechanism of interaction of the two opposing immune responses; pro-inflammatory (Th1) response as a result of HIV infection and the immune regulation (Th2) response during pregnancy that can define the delicate balance of immune response in conjoint cases of HIV infection and pregnancy. Further research is required to address the mechanism of interaction of the two opposing immune responses against HIV infection and the immune regulation during pregnancy that defines the altered immune response.

Clay is a soil with poor characteristics, which include low weight bearing capacity hence it needs to be fixed. Stabilization is a soil improvement technique, involving the use of cement for increase bearing capacity. However the high cost of cement, led to the investigation of other alternatives, e.g. Rice husk ash (RHA), a pozzolanic agricultural waste, which contains a lot of silica, processed by burning husk ash. This study therefore analyses the effect of substituting RHA on the physical and mechanical property of clay, in an attempt to increase the value of its carrying capacity. Laboratory scale testing was based on ASTM standards, which include California Bearing Ratio (CBR) and Unconfined Compression Test (UCT). The variation of RHA applied to the sample were 3%, 6%, 9%, 12% and 15% of the soil (dry density), at a curing period of 0, 3 and 7 days. The results further showed that the optimum value of UCT (1.05 kg / cm²), was obtained at 6% RHA, within a 7-day curing period. The optimum CBR value (13.12%) was obtained with the unsoaked mixture at 9%, with a 7-day curing period.

The DG system uses renewable energy sources which are connected to the conventional power system in order to minimize the real power losses in the power system. 9-bus system will be considered for this analysis. The appropriate location of the DG is identified based on the base case power result, bus voltage and total losses in the system. The STATCOM size and the appropriate location is decided by the voltage profile improvement and real power loss minimization in the system. The proposed work is carried out in PSAT with MATLAB / Simulink environment. The results ensure that the real power losses in the power system network will be minimized by placing DG and STATCOM at suitable locations.

Managing hope and fear in a cultural perspective can be one of the success keys for a nation or organization on any scale. A country that is unable to manage both will become a failed state, as does an organization or even a person. People who are seized with anxiety and unable to turn it into a source of strength will tend terminate their lives by suicide. The leaders of countries incorporated in a certain region are always faced with various threats, challenges and opportunities. This paper tries to describe a number of phenomena that occur in a number of regions which are considered to develop as hope and fear that is analyzed in the perspective of American Studies. The overall description of this paper leads to the conclusion that the ability of political leaders in an area to manage hope and fear will be able to determine the strength of civil society in the region.

Droplet infection is a widespread disease of all age groups. Consciousness about prevention and treatment can reduce the risk of infection. Infected population of any age group can avail a common treatment. In this paper, we have proposed age structured SITR model along with droplet infection. To analyse the model, we have evaluated disease free equilibrium point, endemic equilibrium point and basis reproduction number (R0).It is found that disease free equilibrium point always exists and model is stable around it when R0 <1. Similarly endemic equilibrium point exists and model is stable around it when R0 >1. Sensitivity analysis for basic reproduction number is performed to see the influence of parameters on disease spread. Optimal controls are measured to minimize infected population and produced droplets, using Pontryagin's minimum Principle. Numerical simulation is done to observe the dynamic behaviour of all population in model. Suitable graphs are illustrated to support the results.

Commercial motorcycles and scooters incorporate independent circuits for front and rear brake actuation, thus precluding load-dependent brake force distribution. In all cases of manual brake force modulation between the front and rear wheels, there is poor compensation for the changes in wheel loads on the account of longitudinal weight transfer, thus making it challenging to provide an adequate braking force to each wheel. The ration in which the braking force should be distributed between the front and the rear wheels is dependent on the motorcycle geometry, weight distribution, mechanical sizing of braking system components, and is a variable based on the instantaneous deceleration. This connotes that a fixed bias of front and rear braking forces can be optimized only for a narrow range of motorcycle’s deceleration. Maximum braking performance occurs just prior to wheel lockup, as a sliding tire provides less grip than a rolling tire. This is also the scenario when both the tires are doing the maximum work in decelerating the motorcycle. Therefore an optimal brake force distribution is one that locks both wheels at the same instant. In practice, however, a rider would avoid a front wheel lock-up as it would make the motorcycle challenging to steer. In theory an apt distribution of the braking forces between the front and rear wheels maximizes the overall braking efficiency of the motorcycle whilst reducing its stopping distance. This paper examines plausible performance gains of load sensing brake force distribution in a motorcycle.

Accurate brain tumor segmentation is a challenging task from the Magnetic Resonance Imaging (MRI) in the field of medical image processing. For this purpose, we propose a Novel Center Symmetric-Local Binary Pattern (CS-LBP) and Chi Square Fuzzy C-mean based segmentation via clustering to segment the abnormal tissues from the normal region. Initially, preprocessing is performed to extricate the region of interest based on improved threshold and center symmetric LBP. Then we compare the preprocessing output and original MRI image using Bhattacharya similarity metrics to obtain the region of interest from the imaging technology. Finally, Chi Square distance based Fuzzy C-Mean (CS-FCM) segmentation is performed to cluster the region according to the feature based on region of interest (ROI), including entropy, contrast, and mean for necrosis, edema and enhanced tumor regions. BRATS 2015 dataset is used to evaluate the performance in terms of Jaccard matching, specificity, Positive Predictive Value (PPV) and Dice Similarity Coefficient (DSC). The existing approaches are not efficient and predictive whereas our proposed method performs better in clustering the tumor into three regions (necrosis, edema and enhanced tumor) based on the region of interest.

Hand tractor is a popular agricultural vehicle in Asia, like Indonesia. Most of the hand tractors are used to soil tillage in paddy fields that are integrated with various types of implements such as plow, rotary, dishes, etc. The challenges a majority of the characteristics of paddy fields in Indonesia is sloping land (with a slope greater than 10°), small in size (5-10 m2 per plot paddy field) and irregular in dimensions between one paddy fields land and another. That requires the performance of hand tractors to be able to work moving between plot paddy fields so that it can achieve all plot paddy fields. Several studies have examined this issue for 4-wheel tractors; however, on the hand tractors have not been studied in depth to date. Therefore, the objective of this study is to analyze the performance of the hand tractor to climbing sloping terrain. The experiment of the field for trajectories of hand tractors is designed with a slope of 10°, 15°, and 30°. The performance of the hand tractor (torque, wheel rotational velocity, forward speed, sinkage, and slip) is measured when the hand tractor climb of the track. Traction efficiency is also calculated to show the level of effectiveness of the hand tractor when climbing of sloping land. The results show that the torque on the hand tractor increases with increasing land slope from 10° to 15°. But after that, the torque will decrease sharply in the condition of the land with a slope of 30°. Wheel rotational speed, forward speed, sinkage and slip of the hand tractor decrease by increasing the sloping angle of the land, respectively. The traction efficiency of the hand tractor also decreases along with increasing sloping terrain.

A fraudulent behaviour such as cheating in examinations can hamper the efforts of many students; it is the Machiavellian behaviour of students which is being increased with technology and the rapid growth of the internet. In this paper, we have designed two algorithms, the first algorithm generates automatic sitting arrangement plan for examination halls to prevent mismanagement, prohibited material, and cheating during examinations and the second algorithm deals with Henon chaotic map to rescheduled the sitting plan. It is based on the sitting allocation methodology to generate random allocation in classrooms for every exam to prevent cheating from their surrounding locations. To preserve academic integrity, it is required to decrease the possibility of cheating in the examination hall. Maximum utilization of classrooms and less human resources are the main objectives of the proposed algorithms. Proposed work has been applied to university, and it gives a better environment during examination with the less human resource in a less executable time rather than a manual sitting plan allocation methods.
