Relative location determination in Vehicular Ad Hoc Networks (VANET) is a field of location studies, that researches the exchange of location between vehicles and gives a service for end users to help them, this thesis suggests a new approach for VANET to exchange the location without using Global Positioning System (GPS) map or Roadside Units (RSU), by exchanging the location between vehicles that already have location and update their location or update other vehicles’ location. Other approaches work on GPS and/or RSUs to exchange the location and give the location to the vehicle, but the accuracy of the GPS is not good in some areas or places and some roads have not been equipped with RSUs. The suggested approach consists of three cases; the first case is when a vehicle loses a GPS signal, the second case is to start looking for the location in an area with no GPS coverage, and the last case is the low accuracy of GPS location data. Using this approach will introduce a hybrid system that can give the users many ways to get an accurate location and exchange their location with other vehicles. It can also be utilized for many services that will help companies and service providers. The result confirm that the system can add values to the accuracy with more than 3% from the average of the system of the accuracy that the system have already started with and we can transfer the location data to more than 95% of total nodes.

Indonesia is a multicultural nation with a diversity of identities such as; languages, tribes, religions, and territories spread over thousands of islands in the archipelago. The diversity becomes valuable, but on the other hand, the differences of primordial aspect are often as justified in the conflict on the political in local contestation. Using the primordial aspect as the political instrument, in the sense that the author is called "primordialism on politics" is a phenomenon of local politic contestation. The objective of primordialism on political is an efficient mobilization instrument of politics by saving time, energy, and thought which only arouses the "sociological consciousness of the electorate. Primordialism on politics does not require political actor ideas to gain support but takes advantage of the primordial aspect inherent in each voter. The emergence of primordialism in politics especially on the local political contestation, not only because we are a diverse nation, but there are non-primordial factors such as; political ideas, voting behavior and function of political parties.

This paper describes the design and simulation tests of a system that uses a set of three internal shifting masses (ISMs) that can be displaced along three orthogonal axes, with the purpose to re-adjust the center of mass (CoM) in a nanosat. This procedure will reduce the magnitude of the on-orbit external disturbing torques, re-locating the CoM as close as possible to the geometrical center of the spacecraft. This implementation decreases the power needed to keep the attitude stable along time. Angular rates and angular accelerations, provided by an IMU, are employed by the onboard computer that executes the algorithm for the estimation of the CoM and the magnitude of the displacements needed on every sliding element. The disturbance torques considered were: solar pressure, aerodynamic drag and gravitational gradient. In every control loop CoM deviation is estimated using a recursive least square (RLS) method, the magnitude of the displacements of each ISM is calculated and moved accordingly. In the next step on-board computer identifies the new position of the CoM and the magnitude of the displacements, until the CoM position is within the threshold range, from the geometric center of the spacecraft, established in ± 5 mm. Feasibility of the CoM estimation, and relocation system was performed through numerical simulations using Matlab Simulink considering a 3U Cubesat nanosatellite dynamic model.

The construction industry in Indonesia is progressing rapidly. Contractors are required to complete construction projects in a short amount of time, with minimal costs and efficient utilisation of human resources. The BIM method is 3D modelling technique containing all the construction information that works during the planning, design, implementation, and maintenance phases. BIM has the concept of 3D approach (modelling) to 7D (facility management applications). Several contractors in Indonesia have initiated the implementation of the BIM method for project construction in the construction phase, including the high-rise building construction category. This study discovers the achievement level of BIM implementation in the construction phase by contractors in Indonesia who have already implemented BIM. Data research was obtained from a questionnaire, using two methods of data analysis, Building Information Modeling Implementation Index (BIMII), and Importance Performance Analysis of Building Information Modeling (IPABIM). There are 25 criteria divided into four categories: people, cost, time, and integration. Calculations of BIMII produce a quite achieved score of 67.46%, with categories as follows: people, quite achieved, 62.47%; cost, achieved, 71.64%; time, achieved, 69.41%; integration, quite achieved, 66.32%. The IPABIM classifies the categories of achievement level of BIM implementation into four categories: quadrant A, areas of improvement, eight criteria; quadrant B, excellent work, 15 criteria; quadrant C, low priority, one criteria; quadrant D, disproportionate, one criteria. These findings give meaningful contributions for understanding the achievement level of BIM implementation in Indonesia.

Food production is everybody’s concern. One of the aspects that can be looked into is the fishing sector that is a good source of livelihood and food, as well. Fishing directly from the rich Philippine natural water resources can’t sustain the increasing people's demand on fish. Fish is essential to one’s meal due to proteins and nutrients derived from it. To address such concern, aquaculture is deemed necessary. Aquaculture plays a significant role in increasing fish production to sustain the people’s need and demand in various life aspects. In the Philippines, Regions 1(Ilocos region) and 2 (Cagayan Valley) are known growers of Siganid (Siganus guttatus). Said species can be claimed as a promising commodity due to its meat quality and taste. Along this study, the aquaculture activities; distinct features of value chains; roles and activities of the intermediate, major support, other linkages; and, the value addition contributed by each player were answered. Industry assessment and surveys were conducted to determine the market distribution of S. guttatus, thus; public officials’ assistance and rural folks were tapped to trace the major producing areas. From the identified regions, a value chain map wherein traders (wholesalers) served as the link between chain players was established. Value chain analysis (VCA) framework was used in data analysis. Results of the survey were presented and validated in a focus group discussion (FGD) with the participants representing different actors of the siganid aquaculture chain and support agency enablers. Results showed that the production environments of siganid aquaculture, farming systems and distinct features of value chains vary in both regions, however; they do not differ on farming technology and production scale. There was a significant interplay between and among the intermediate suppliers, key role players, support services and other linkages in both regions. The product flow showed that market distribution was limited since it was just within the provinces of identified regions. With regards to value addition, grow-out operators S. guttatus contributed most in region one (1) while fry collectors added more than half of the total share in Cagayan Valley.

We summarized other researchers work and summarized some challenges in virtual teams. Due to the time and resource limitation, although we covered the common challenges in a virtual environment; we might still miss some. Virtual leaders need to notice that those challenges are interrelated with each other. It’s not wise to just focus on some of them and ignore others. Getting familiar with the relationships among those challenges and how they affect each other will be very helpful for leadership effectiveness in virtual teams. Team leaders will need more training, specifically in delegation. Given that, team members need to be able to share leadership responsibilities and training programs ought to be developed in recognition and support of that. A contribution to this problem is that few companies have extensive expertise in how to operate and engage in virtual teams, and they create them without understanding how they differ from regular team.

Use of Mobile/Wireless ad hoc networks (MANET) is growing mostly in situations there is need for temporary data exchange such as in emergency services, conference meetings, virtual classrooms due to their low cost and easy in setting up, since they are infrastructure-less. However none existence of centralized administration of standard support services, dynamic topology, and air interface makes them highly vulnerable to attacks. The autonomous nature of the network results in security solutions being implemented mainly at the nodes, which are resource constrained i.e. limited computing power and memory, low bandwidth, and low battery life, thereby limiting the tightness of these solutions. It is extremely important to have flexible and robust methods of detecting attacks and their sources looking at the diversity of MANET application areas, so that appropriate countermeasures can be put in place. Detection based schemes can be incorporated to complement prevention techniques implemented in the network protocols. These methods should work through the whole protocol stack since attacks target specific layers. This paper discusses MANET attacks detection methods that are currently in use taking note of their performance. In the paper we also suggest a hybrid cross layer approach capable of detecting more than one known and new attacks, which can be researched on to complement existing methods in building effective security solutions for MANET.

The growth in electronic transactions has resulted in a greater demand for fast and accurate user identification and authentication. Conventional method of identification based on possession of pin and password are not all together reliable. Higher acceptability and convenience of credit card for purchases has not only given personal comfort to customers but also attracted a large number of attackers. As a result, credit card payment systems must be supported by efficient fraud detection capability for minimizing unwanted activities by fraudster’s. Most of the well-known algorithms for fraud detection are based on supervised training. Every cardholder has a certain shopping behaviour, which establishes an activity profile for him. Existing fraud detection systems try to capture behavioural patterns as rules which are static. This becomes ineffective when cardholder develops new patterns. This paper aimed at developing credit card fraud detection system for banking industries in Nigeria using adaptive data mining and intelligent agents that could combines evidences from current as well as past behaviour and to determine the suspicious level of each incoming transaction. The statistics of fraud in Nigeria is discussed. In this paper, a system model for credit card fraud is discussed and designed.

Currently, remote vision-based control, which is converted into a voice, is a research becoming one of the major focuses among researchers due to various applications in terms of Human-Computer-Interaction (HCI). The proposed idea is to learn a robot how to receive hand directional gestures as left, right, up and down, and pronounce these directions according to the originated directions. To implement this, a technique is proposed by using index-finger of a hand in order to point out random directions, in which the feature extraction is based on the area of the object pixels. It is static hand directional gesture recognition. This method starts by inserting a video to extract frames, which are processed one by one to output 4-possible-direction. After that, each specific direction will switch on its corresponding voice pronouncing the direction sign as a robot speaking. Experiments were conducted on 10-video frames for testing by using 10 individuals. The total frames for this experiment is having 442 frames. Results demonstrate high successful recognition rate in terms the performance accuracy up to 94.57%.

Abuja has not been considered as a thing in itself because the inhabitants have not perceived the city as a place to live and meet life obligations. The architecture of Abuja has gone through changes from the original interest of the Master Plan of the city. The Abuja urban actors have not worked to create different urban models, using the basic urban elements of enclaves, armature and heterotopia. It has not occurred to them, that, a beautiful and delightful city environment is an oddity, some would say, an impossibility because of the poor implementation of the Abuja Master Plan and the use of nonprofessional in the execution of the principles of the Master Plan. These resulted in slum settlements within the Central City area, inadequacy of housing, a greater population of the inhabitants are without decent places to live and resorted to living in make-shift homes, the architecture of the urban poor, in Abuja.

Food allergy is a major health issue for the human body in industrialized countries and has increased significantly in the past decade. Food intolerance must be distinguished from food allergies and, furthermore, these allergies should be classified into either immunoglobulin E (IgE), Non-IgE, or a mixed response. The clinical attributes vary from life-threatening anaphylaxis to milder IgE-mediated responses, atopic dermatitis, and gastrointestinal symptoms. Milk, soybean, egg, wheat, and peanut allergies are common in children, whereas peanut, tree nuts, fish, and shellfish allergies are common in adults. The digestive allergies, skin allergies, and respiratory allergies are the most common allergies among children. Diagnostic work up must be guided by the clinical history, and consumption of fortified gluten-free bakery products instead of wheat products is necessary for celiac disease (CD) patients. Most current allergen detection methods are immunoassays, such as ELISA. Skin testing and food-specific IgE done by standard methods are very useful. Combination of skin prick test and patch test is useful tool for the diagnosis of food hypersensitivity in children with atopic dermatitis.
