A study of MPEG series
The applications of audio and video compression are limitless and the ISO has done well to provide standards which are appropriate to the wide range of possible compression products. MPEG coding embraces video pictures from the tiny screen of a videophone to the high-definition images needed for electronic cinema. Audio coding stretches from speech-grade mono to multichannel surround sound. This paper presents an overview of the video compression standards related to the MPEG family. MPEG-7 and MPEG-21 are specially covered including its latest standards. MPEG-7 is mainly used for object descriptions and MPEG-21 is for DRM (Digital Rights Management).

Spectroscopic studies of L-Cysteine: DFT calculations
The infrared and Raman spectra of L-cysteine molecule has been recorded in the nujol mull as well as in the aqueous solution in the range of 4000-400cm-1. The observed infrared and Raman frequencies are assigned on the basis of the theoretically calculated vibrational frequencies for the most stable structure of zwitterionic cysteine hydrated with six water molecules at B3LYP/6-311G* level. The electronic absorption spectrum of the cysteine molecule has been measured in solution at different concentrations and at different pH in the range of 400- 200 nm. It is observed that the electronic absorption band shifts with the change of pH as well as the concentrations. The TDDFT calculations for the same molecule (zwitterionic cysteine + six water molecules) has also been carried out at B3LYP/6-311G* level. The optimized bond lengths and bond angles for the most stable structure of cysteine hydrated with six water molecules were compared with those reported for X-ray data for cysteine.

Experimental investigation of compressed ignition engine using cotton seed oil methyl ester as alternative fuel
This paper gives the brief out line about the worldwide production cottonseed & its oil, Cotton Seed Oil (CSO) properties, its comparison with diesel and Jatropha biodiesel. It investigates the performance of a diesel engine using diesel fuel and cottonseed oil (CSO) biodiesel in terms of brake thermal efficiency and indicated thermal efficiency for conventional diesel, cottonseed oil, as well as for Jatropha oil. For this aim, A Single Cylinder, 4-stroke vertical, water-cooled, self-governed diesel engine developing 5 HP at 1500 rpm (Rope brake dynamometer with spring balances and loading screw. Brake drum diameter = 0.400 m.) engine is selected for the testing with diesel fuel and neat bio-diesel, which is cottonseed oil methyl ester, at full load conditions. The evaluation of theoretical data showed that the brake thermal efficiency and indicated thermal efficiency of CSO biodiesel was slightly higher than that of diesel fuel and Jatropha oil. This study reveals that the use of cottonseed oil biodiesel improves the performance parameters of CI engine compared to conventional diesel fuel.

Corean: A proposed Model for Predicting Effort Estimation having Reuse
The estimation accuracy has been focused in various formal estimation models in recent research initiatives. The formal estimation models were developed to measure lines of code and function points in the software projects but most of them failed to improve accuracy in estimation. The concept of reusability in software development in estimating effort using artificial neural network is focused in this paper. Incorporation of reusability metrics in COCOMO II may yield better results. In COCOMO II it is very difficult to find the values of size parameters. A new model called COREAN has been proposed in this paper for better effort estimation accuracy and reliability. The proposed model has focused on two components of COCOMO II. First, instead of using RUSE cost driver, three new reuse cost drivers are introduced. Second, In order to reduce the project cost, three cost drivers such as PEXE, AEXE, LTEX are combined into single cost driver Personnel Experience (PLEX). Finally, this proposed model accuracy is more improved with the help of Enhanced RPROP algorithm and simulated annealing optimization technique.

Characterization and antimicrobial susceptibility patterns of clinical salmonella isolates from Nandi County of rift valley, Kenya
Salmonellosis, a water and foodborne infection is a major cause of high morbidity and mortality in Sub-Saharan Africa. Its prevalence and mortality has been associated with antibiotic resistance related strains that calls for specific strain identification. Data on prevalence and antimicrobial susceptibility patterns of Salmonella in Nandi County of Rift Valley is scarce despite the scourging effect of the disease. 200 stool samples were collected from patients treated for diarrhoea at Kapsabet District hospital between (February – November, 2011). 84%(n=168) were positive for various bacteria isolates as determined by standard microbiological culture techniques. 29%(n=48) were Salmonella. The distribution was; S.typhimurium 56%(n=27),S. enteritidis 29%(n=14),S.paratyphi C 6%(n=3), S. paratyphi A 4%(n=2), S.gallinarum 2%(n=1),S. dublin 2%(n=1). Isolates were confirmed by API 20E biochemical system in addition to invA gene sequencing. All Salmonella isolates were resistant to ampicillin, (19%) were resistant to sulfamethoxazole .Resistance to tetracycline, streptomycin and chloramphenicol was (6%).All ampicillin resistant isolates possessed blaTEM gene while sulfamethoxazole resistant isolates had sul2 gene both genes are associated with class1 integrons. The findings indicated a low antimicrobial resistance in relation to other regions within the country. This situation should be encouraged. Additional safety measures should include training in personal hygiene, sanitation and ensuring water quality.

Modelling of flow curve of IF steel sheets using artificial neural network
Several investigations have established that the formability of sheet metal can be assessed from the stress-strain relationship(Sing,W.M and Rao,K.P[1997]). A true stress-strain curve is frequently called a flow curve because it gives the stress required to cause the metal to flow plastically to any given strain. In this paper the flow curve is used for modelling. A model based on an Artificial Neural Network (ANN) is introduced to reveal the flow curve of IF steel of thickness 0.85 mm non-coated. After using experimental data to train and test it, the model is applied to new data for prediction of the flow curve. Flow curve represents the basic plastic flow characteristics of the material.
