Permissions based malware detection system for android a review and surveys
Number of smartphones users is increasing rapidly and Android is currently the most popular Smartphone operating system. However, users feel their private information at threat, facing a rapidly increasing number of malwares for Android which significantly increasing that of other platforms. There are large number of apps available for the ease and use of the smartphone users. When a user installs any application from the google play store he/she is asked to grant some permissions to function the particular application properly. User either has to accept all those permissions in order to install the application on his/her device or he/she has to deny all those permission and terminate the installation of the application. A normal smartphone user is not aware of most of the permissions asked during installation so he/she tends to accept those all permissions in order to use the application. This introduces a potential threat to the users device. With this smartphones usage, mobile malware attacks are also growing. The application that we are developing will help user to identify the malicious applications that are installed on the device. And if a user finds any malicious activity being performed by any application then he/she can change the necessary permissions to avoid the malicious activity being done by the application. All this will be done post the installation of any application. So user will first have to accept all those permissions and get the app installed on his/her device from the Google play store. And then user can modify (allow/deny) the permissions the application is using. Our proposed application will have a scanning activity which will tell the user which applications are malicious and may harm the device. The application will use machine learning approach to some extent for scanning the applications to determine the application is malicious or not.

Determination of varriation of soil characteristic due to lime stabilization
Generally the soil quality improvements through stabilization include better soil gradation, reduction of plasticity index or swelling potential, and increases in durability and in strength. The tensile strength and stiffness of a soil layer can be improved through the use of additives and thereby permit a reduction in the thickness of the stabilized layer and overlying layers within the pavement system. According to Sherwood (1995) and Little (1999), lime stabilization can be used to either modify or stabilize clays. The strength of lime mixture depends to a great extent on the quantity of lime added above lime fixation point. (i.e. it changes the Plasticity Index of soil). In this experiment Indian A-7a type black cotton sol is used. In this paper soil subgrade characteristics are determined by using 0%, 3%, 6%, 9%, 12%, lime ( by weight of soil) stabilization techniques & a graphical representation is made % of stabilization Vs PI values. So gradually PI value of soil decreases. But some time in the field plasticity of soil, especially black cotton soil changes very rapidly in this case the advantage of this graph is one can easily get some rough idea about changes soil characteristics due to applications of lime stabilization, when the soil becomes highly plastic to non plastic. Finally a semi empirical formula is made to get an idea about Plastic Index value of A-7a type black cotton soil (As per Highway Research Board of India) due to application of lime stabilization within range of 0 to 12% of lime by weight of soil. This paper also help full to determine how the subgrade strength varies with lime stabilization.

Carcass parameters and sensory characteristics of broilers fed diets containing palm (elaeis guineensis) kernel oil residue
Palm Kernel Oil Residue (PKOR) is a waste product obtained after extracting oil from palm kernel by cottage industries. The residue is dumped at processing sites and the stench that emanates from the oxidizing product, causes nuisance to processors and nearby residents. Animal scientists are advocating the use of the fresh product as energy resource in broiler rations. This study was therefore conducted to determine the effects of partial replacement of maize in broiler rations with PKOR, on carcass parameters and sensory characteristics of broiler chicken. A total of 80 birds (5 from each treatment) were randomly selected from 160 birds fed diets containing 0% (control), 2.5%, 5.0%, 7.5%, 10%, 12.5%, 15% and 17.5% PKOR. At maturity (8 weeks old), the birds were slaughtered, and hot carcass and viscera weights were taken. Carcasses were sectioned into primal cuts after 24-hour chilling, and each part was weighed. The breast muscles were grilled for sensory evaluation. Proximate composition, ultimate pH (pHu) and peroxide value of the muscles were determined. Data obtained were analyzed using the General Linear Model of ANOVA component of Minitab software. The results indicate that PKOR inclusion up to 17.5% in broiler rations has no significant (p>0.05) effects on carcass parameters and sensory characteristics of the meat. Crude protein and fat contents of the carcasses were not significantly (p>0.05) different. However, PKOR inclusions beyond 7.5% significantly (p<0.001) increased the moisture content of the muscles. Ultimate pH (pH after 24hours of slaughter) and peroxide value after 7 days in storage were not significantly affected by the use of PKOR. The study indicated that farmers can include PKOR up to 17.5% in broiler rations without adverse effects on the carcass and sensory characteristics of the meat.

Developing a bead geometry based criterion for selection of process parameters of metal inert gas (mig) welding using taguchi techniques
Metal inert gas (MIG) welding is a fusion welding process having wide applications in industry. In any welding process, proper selection of input parameters is necessary to obtain good quality welds and consequently, increase the productivity of the process. Invariably, quality of welds is specified in terms of their ability to meet the service load requirements, zero-defect condition and/or cost-effective production. However, it is observed that a ‘Good Weld Bead Geometry’ can often be used to stipulate the weld quality as well as ensures one or more of the former considerations. The weld bead geometry is expressed in terms of six output parameters (called responses), viz., height of reinforcement (R), depth of penetration (P), weld bead width (W), per cent dilution (%D) and shape relationships such as weld penetration shape factor (W/P) and weld reinforcement form factor (W/R). This paper reports the experimental work with regard to developing a bead geometry-based criterion for acceptance of weldments prepared by MIG. Taguchi design method, comprising L16 orthogonal array (OA) was used to conduct the experimental with two replications and graphical method of analysis was used to arrive at the optimum combination of process parameters. The Responses were expressed in terms of six input process parameters, namely, wire feed rate (WFR), arc voltage (V), welding speed (WS), stand-off-distance (SOD), shielding gas flow rate (GFR) and parent material plate thickness (PT). Influence of the six main factors and their two-factor interactions were studied and the results are presented. It is observed that an increase in parameters like wire feed rate, welding speed, SOD and plate thickness will also result in a corresponding increase in reinforcement while they affect penetration in a negative way. On the other hand, a decrease in arc voltage results in an increase in reinforcement, but penetration decreases. The effect of GFR is typical, in the sense, as it is increased reinforcement decreases, but penetration shows an increasing trend. Further, weld bead width shows a positive correspondence with almost all input parameters. But, it has a negative relationship with SOD while it is unaffected by GFR. Also, the effect of 2-factor interactions have been studied and presented in this paper.

Normalized impact factor – nif (IF )
This study developed a new framework for evaluating the impact of an article/author/journal. The importance of research evaluation is identified. The inadequacies of the methodologies presently used to evaluate impact of published research are also identified. A normalized impact factor which is a citation based metric tool is developed. The frequencies of citation of a reference within an article were used to determine the imaginary and the real impacts of the cited reference. The development of the normalized impact factor is based on the opinion that not all citations made in an article should count in the computation of the impact of a publication.

Separation cordial labeling of graphs
This paper introduces a new type of labeling called separation cordial labeling. A separation cordial labeling of graph G is a bijection f from V to {1,2,… ,|V|} such that each edge uv is assigned the label 1 if f(u) + f(v) is an odd number and label 0 if f(u) + f(v) is an even number. Then the number of edges labeled 0 and the number of edges labeled 1 differ by at most 1. If a graph has a separation cordial labeling, then it is called separation cordial graph. Here, the class? Pl?_n ( n ? 5), ?Pl?_(m,n) (m,n ? 3) of planar graphs, full binary tree, the star graph? K?_(1,q), the complete bipartite graph K_(m ,n), path P_n, the cycle? C?_n, are discussed and found to be separation cordial. Also, found that complete graph K_n is not separation cordial for, n ? 4.

Determination of major elemental contents of some bentonitic clay in Akwa Ibom State, Nigeria
Clay as a mineral resource remains an important material for most industries. They are varied in composition and as a result serve a multitude of purposes. To ascertain the industrial application of each clay type, knowledge of the elemental contents of the clay is important. For clays with montmorillonitic content, they are used in oil and gas industries mostly as drilling fluid viscosifiers. In this study, five clay samples obtained from clay deposits at Ibiono, Ini, Itu, Ikono and Uyo in Akwa Ibom State, Nigeria were characterized elementally to evaluate their montmorillonite content potential for use as drilling mud viscosifiers. X-Ray Fluorescence (XRF) coupled with samples dilution method and standard calibration of samples was used. The elemental analyses portray montmorillonite as the dominant clay mineral in the Ini, Itu Ibiono and Uyo clays. Abundance of major elements showed that SiO2 (10.4 - 42.4%) and Al2O3 (4.4 -15.4%) constitute over 70% of the bulk chemical compositions. Other constituents included Fe2O3, K2O, CaO, Na2O, MgO among others. Additionally, notable disparities exist in the SiO2 and Al2O3 contents of the clays, the Itu clay was the most siliceous while the Ikono clay was the least aluminous compared to the others. Furthermore, the XRF analysis of the clays showed that the Al2O3/SiO2 ratio was higher than 0.38; as expected for montmorillonite content of clays. Therefore, the elemental characteristics of the studied clays revealed that they are suitable for use as drilling mud viscosifiers provided appropriate beneficiation is carried out on them to activate their Calcium-based to Sodium-based bentonitic clays.
