Sanskrit,called the mother of all Indian languages, plays important role in Indian literature. All the Indian languages are expected to be derived from Sanskrit language. If we change the order of words in formation of the Sentences in Sanskrit, the meaning will remain same i.e., Sanskrit is free ordering language (or syntax free language) and there is no ambiguity in the form of the words even if the order changes. Morphological analysis is a core component of language processing for Indian languages .Complexities involved in spell checking of documents in Sanskrit can be analyzed. We have applied morphological analysis to a large number of words in different parts of speech. A spellchecker based on this analysis has been developed. This paper proposes the architecture of the spellchecker and the spell-checking algorithm based on morphological rules

A 2-component composite filler- binder was designed and evaluated for direct compression properties. Tapioca starch (NTS) was modified physically at molecular level by annealing and enzyme hydrolyzed to obtain microcrystalline tapioca starch (MCTS) which was coprocessed with α-lactose monohydrate (LMH) to form Microcrystarlac (MSL). NTS was extracted from cassava tuber (Mannihot esculenta crantz) using a standard method. The powder suspensions were prepared in concentration of 40 %w/w in five separate conical flasks. The starch granules were annealed for 1 h and subsequently hydrolyzed with α-amylase at 58o and pH 7 for 1, 2, 3, 4, and 5 h in a water bath. The reaction was terminated and neutralized with 0.1 N HCL and 0.1 N NaOH respectively. The MCTS was washed, recovered by sedimentation and air dried at room temperature for 72 h. Following characterization, the granules that were modified for 3 h, sieved fraction >75-250 µm was coprocessed with α- lactose monohydrate (α-LMH) at concentrations of 10 to 50 % w/w as a dried mass relative to MCTS. Granule size ranges >75 - 250 µm, and >90 - 250 µm were characterized and compacted at a range of compression load 2.5 to 12.5 KN. Average flow rate, angle of repose and compressibility index were 3 g/s, 32o, 22 % respectively for MSL (granule size range >90 - 250 µm and component ratio, 50:50). The corresponding values for the direct physical mixture of MCTS and lactose are 0.65 g/s, 40o, 53 % respectively. MSL shows improved functionality over direct physical mixture of the primary excipients. MSL was compared with Starlac®, Cellactose® and MCC. The onset of plastic deformation Py (yield value) are: Cellactose (24.2 MNm-2)>MCC (25 MNm-2 )>MSL (68 MNm-2)>Starlac (143 MNm-2). The degree of plastic deformation occurring during compression (Pk) is in the following order: MSL (16.4 MNm-2)>Starlac®(17 MNm-2)>MCC (18.6 MNm-2)>Cellactose® (19.1 MNm-2). MSL is more superior in functionality than Starlac, Cellactose and MCC. The dilution potential obtained for MSL when compacted with paracetamol (PCM) and ascorbic acid (AA) as active drug (API) were: 45 %w/w PCM with MSL, 30 %w/w AA with MSL. The hardness of MSL containing 45 %w/w PCM, was 80 N. MSL can be employed to formulate harder tablet especially poorly soluble and poorly compressible API. Key words: Microcrystarlac, Coprocessed, Direct compression, Filler-binder, Microcrystalline Tapioca Starch.

In this work free-volume parameters needed for poly(styrene) – p-xylene-tetrahydrofuran coating and poly(methylmethacrylate) – tetrahydrofuran – ethylbenzene coatings were estimated by minimizing the difference between model predicted residual solvent and experimental residual solvent in binary coatings. Each ternary system needs two binary systems for example poly (styrene)-p-xylene-tetrahydrofuran system needs poly(styrene)-p-xylene and poly(styrene) – tetrahydrofuran.

In this paper, a novel pre-processing algorithm is introduced to identify the principal lines from a palm-print image and a discrete cosine transform (DCT) domain feature extraction algorithm is then employed for palm-print recognition, which can efficiently capture the spatial variations in the principal lines of a palm-print image. The entire image is segmented into several small spatial modules. The task of feature extraction is carried out in local zones using two dimensional discrete cosine transform (2D-DCT). The proposed dominant DCT-domain feature selection algorithm offers an advantage of very low feature dimension and it is capable of capturing precisely the detail variations within the palm-print image. It is shown that because of the pre-processing step, the discriminating capabilities of the proposed features are enhanced, which results in a very high within-class compactness and between-class separability of the extracted features. From our extensive experimentations on different palm-print databases, it is found that the performance of the proposed method in terms of recognition accuracy and computational complexity is superior to that of some of the recent methods.

With the proliferation of electronic systems within automobiles, using CAN(Control Area Network) for all automotive electronics becomes prohibitively expensive and complex. Recently another communication standard called LIN (local inter connect network) has emerged as a viable replacement to CAN. LIN is a simple and low cost solution to reduce the complexity and the cost of the overall automotive network. A combination of CAN and LIN when required and dedicated can be used to reduce the cost of automation in industries in a significant way. Also such a hierarchical network can be used effectively in conjunction with a SCADA system based on Virtual Instrumentation for monitoring and control by a virtual control panel(Touch screen LCD) located in the instrument cluster of the vehicle according to OBD-II(On Board Diagnostics) regulations

Solar photovoltaic are extensively used as an alternative power source in gridless low grid electrified places for home lighting system such as portable lantern lighting, street lighting and home/community house lighting applications. Presently Sodium vapour(SV) lamps or CFL lamps are being used in these houses. With the advent of LED lamps which give lumen efficiencies as high as 110-140 lumen/W, the solidstate lighting is becoming a competitve technology to the conventional SV /CFL technology. The penentration of LED technology is through downsizing of the lamp size, low power requirement as compared to conventional lighting system. Besides reducing the cost of the LED lamps, major reduction in solar(PV) module cost is achieved through this downsized replacement option. Investigation study reveals that the optimization of lighting with solar powered LED lamps are feasible to meet lighting requirement in houses as well as in community placs due tto its low power consumption Thus it is concluded after investigation that solar powered LED lamps can be cost effective due to low sizing of solar pannel as compared with large sizing of conventional lamps. The study also reveals that iIts impact on indian rural society may provide potential youths an opportunity to become literate in vocational trades.

In this work, we propose a novel Network Intrusion Detection Systems (NIDSs) architecture utilizing the misuse detection approach. This Network Intrusion Detection System architecture utilizes misuse detection agent. The proposed misuse detection agent adopts the novel framework by using Java Expert System Shell (JESS) and Snort rules along with the integration of multi agents. This approach achieves efficient misuse detection by detecting various types of network attacks and improves system performance. This approach introduces the framework for the network database security by implementation of a real time monitoring system using multi-agents. The NIDS uses the set of rules which defines the misuse behavior of user. This rule generation system is used based on JESS and Snort rules in order to use the rules for well known attacks and then taking the further decisions depended on multi-agents before intrusion occurs.

A Network intrusion detection system (NIDS) is gaining ever increasing importance in security of the information from network attacks. For better system performance and lesser response time an improved NIDS system is proposed anomaly detection is achieved by using various agents and by implementing adaptive threshold algorithm. Thus utilizing multi agents into the improved NIDS system enhances the system performance and response time, yet achieves higher accuracy and broader spectrum of protection from different types of intrusion attacks. in this work we propose the simple technique of Adaptive Threshold Algorithm that can be used to achieve large improvements in the performance of anomaly agent with using multi agents and less complex structure avoiding dead locks, less bulky operations and faster system response time.

Plates and plate-type structures have gained a special importance and notably increased engineering applications in recent years. A large number of structural components in engineering structures can be classified as plates. Plates are also indispensable in ship building and aerospace industries. The wings and a large part of the fuselage of an aircraft, for example, consist of a slightly curved plate skin with an array of stiffened ribs. The hull of a ship, its deck and its super structure are further examples of stiffened plate structures. Plates with variable thickness are also have a great importance in a wide variety of engineering applications i.e. nuclear reactor, aeronautical field, naval structure, submarine, earth-quake resistors etc. A mathematical model is presented for the use of engineers and research workers in space technology have to operate under elevated temperatures. In this paper, the thickness varies linearly in x- direction and thermal effect is varying linearly in two directions. Rayleigh Ritz method is used to evaluate the fundamental frequencies. Both the modes of the frequency are calculated for the various values of taper parameters and thermal gradient.

Phase-transfer catalysis (PTC) has been widely used for the synthesis of organic compounds for more than three decades. Phase transfer catalysis (PTC) uses catalytic amounts of phase transfer agents which facilitate interphase transfer of species, making reactions between reagents in two immiscible phases possible. PTC is used widely in the synthesis of various organic chemicals in both liquid-liquid and solid-liquid systems. The scope and mechanistic features of PTC have been the aim of numerous studies. The use of PTC combined with other rate enhancement techniques like sonochemistry, microwaves, electroorganic synthesis, and photochemistry, is being increasingly explored. Applications in this area in the manufacture of organic intermediates and fine chemicals seem almost unlimited.
