Statical Analysis

The prevalence of the smart phones, the large market share of android and the openness of the android market make android more sensitive platform for malware attacks. For understanding the threat to security and privacy it is important to analyze the behavior of the malicious application. For a forensic point of view an analyst need to understand the behavior of the application to find out the suspicious application In this paper, we are focusing on a different type of android malware analysis techniques: static analysis, dynamic analysis and hybrid analysis (combination of static and dynamic analysis). This paper also presence different methods of these analyses along with their functionality and working.Comparisons of these analyses have been done along with their advantages and disadvantages.

This study was conducted on the universal crude oil samples for the purpose of understanding the relationships between some of the characteristics that control the oil quality. Data were collected from previous works, includingspecific gravity and weight percent of 13 crude oil samples as well as the API and S% of138 crude oil samples belong to oil reservoirs located in the different parts of the world.The APIagainstboth of specific gravity and weight percent (kg/m 3)is governed byaninverse perfect linear regression (r=-0.98) with a better prediction (96%) for the outcomes data. The API relies not only sulfur content, but there are other parameters control the oil density, where the API° is exponentially correlated with S%.

Hasil perancangan yang telah dilakukan secara perhitungan manual kemudian diinputkan untuk pemodelan numerik dengan bantuan software SACS 5.7 lalu dilakukan berbagai analisis yakni analisis pada Member Unity Check (UC), Beban Vertikal dan Horizontal, dan Joint Displacement. Namun yang terpenting atau acuan dalam melakukan redesign agar memiliki struktur yang kaut adalah berdasarkan hasil analisis UC sebab akan mengetahui hasil dari rasio tegangan sebenarnya dengan tegangan izin (A36).

Leaf spring is a simple form of suspension Spring used to absorb vibrations induced during the Motion of a vehicle. The automobile industry has shown Increased interest in the replacement of steel leaf spring (55 Si 7) with composite leaf spring (E-glass/Epoxy) and Jute/ glass epoxy due to high strength to weight ratio, Higher stiffness, high impact energy absorption and lesser Stresses. This research is aimed to investigate the suitability of natural and synthetic fiber reinforced hybrid composite material in automobile leaf spring application. By using natural fibers efforts have been made to reduce the cost and weight of leaf spring. In this work an attempt is made to develop a natural and synthetic fiber enforced hybrid composite material with optimum properties so that can replace the existing synthetic fiber reinforced composite material n automobile leaf spring. Jute and E-glass woven roving mats are used as reinforcements and epoxy resin LY556 is used as the matrix material. The CAD models of Leaf spring are prepared in CATIA V5 and imported in static structural analysis work bench of Ansys14.5 where ignite element analysis (FEA) is performed. The design constraints are stresses and deflections. This study gives a comparative analysis between steel leaf spring and Jute/E glass reinforced Epoxy leaf spring. The hybrid composite leaf spring is found to have lesser weight, lesser cost, lesser stresses and higher stiffness.

ABSTRACT:
This research aims to develop synthetic monthly stream flow data to achieve a sufficient inflow data
for existing and proposed reservoirs on Tigris River in Turkey (GAP project) .These synthetic series
can be used in order to operate these reservoirs to determine the discharges at Iraqi border after
implementation of the future dams. Stochastic analysis for available time series by testing the
homogeneity, stationarity of data, normality, and periodicity .Systematic approach of hydrologic
time series modeling used to identify the model, type of parameters, estimation of parameters for
both Autoregressive AR (p) and Autoregressive Moving Average ARMA (p, q).By using Test, it is
found that the second one is more suitable for derive the required synthetic time series. To preserve
the mutual dependence between sites moreover the preservation of the statistical characteristic of
the time series, ARMA (1, 1) adopted. Matrix of residuals for this model determined .Ten
synthetic time series generated by model demonstrates reasonable results for mean, standard
deviation and skewness coefficient ,moreover, for the matrix of residuals of ARMA(1,1) model.

In this paper the 3D model of the real wheel rim was designed using Autodesk Inventor and finite element analysis is performed using Nastran software by applying restrictions and loads conditions. The materials taken for static analysis are steel, aluminum alloy, magnesium alloy and titanium alloy. Following the comparative study for the four models, it can be specified that the importance of the material for the construction of the rims depends on the mass properties and their design.

Inizio questa breve nota con due analisi di carattere generale, per lo studio concettuale delle catenarie: l'omogenea e l'omnis generis. Da un punto di vista geometrico - statico, il modello di una fune a sezione costante, appesa alle sue estremità, assume una forma geometrica ben definita, che sembra ma non è una parabola, denominata catenaria omogenea communis o vulgaris [Huygens, Leibnitz, Bernulli, Eulero...]. Se, invece, la fune sostiene altri pesi, oltre al proprio (costante lungo la sua curva), la forma geometrica che assume la fune è quella della catenaria omnis generis o funicularia. Nel glossario dei trattati di meccanica catenaria e funicularia sono sinonimi, in quanto indicano il medesimo modello di curva. Ho provato anche a formalizzare analiticamente la funicolare a tutto sesto che, per la paradossale situazione limite fu causa di critiche e di derisione accademica per De la Hire alla fine del '600, ma non per Coulomb, che, sebbene giungesse alla stessa situazione limite nella sua teoria dell'arco a conci privi d'attrito, non ebbe alcuna critica da parte del mondo accademico nel '700. La realizzazione sperimentale della funicolare a tutto sesto, per quanto approssimata dato il numero limitato di carichi da me utilizzati, conferma l'assoluta idoneità progettuale del metodo sperimentale rispetto all'indagine teorica che, in questo caso, come ho detto, porta a situazioni limite innaturali. Nei paragrafi 4 e 5 presento alcuni modelli funicolari realizzati al fine di osservare la variazione della forma di una catenella al variare dei carichi appesi. Dal momento che l'entità dei carichi generatori di forme può essere facilmente determinata per via analitica o grafica in base alle leggi e ai teoremi della statica, è lecito chiedersi: perché ancora sperimentare? Scienza ed esperienza sono due facoltà umane - l'una deduttiva, l'altra induttiva - considerate antitetiche almeno dai tempi di Aristotele (se non prima) fino alle incompatibili posizioni estreme, assunte da empiristi e da razionalisti, nella storia della scienza e della filosofia. Oggi, invece, si può osservare che in tutti i campi della ricerca c'è piena collaborazione tra scienziati teorici e scienziati sperimentali. Dal punto di vista didattico non è così, almeno nel campo specifico della meccanica e della scienza delle costruzioni: la formazione teorica prevale ancora sulla pratica sperimentale. Il culmine del predominio dottrinale si è raggiunto alla fine del '700 con Joseph-Louis Lagrange che dal suo testo di meccanica razionale aveva abolito perfino le figure in quanto casi particolari.

The skeleton frames the fundamental structure of the cutting edge car. Countless plans in squeezed steel outline structure a skeleton on which the motor, wheels, hub congregations, transmission, directing instrument, brakes, and suspension individuals are mounted. During the assembling procedure the body is deftly rushed to the suspension. For vehicles, frame comprises of a get together of all the basic pieces of a truck (without the body) to be prepared for procedure out and about. In our undertaking, the displaying of body by utilizing CREO programming, by taking the information from the past diary paper for six-wheeler skeleton. Present utilized material for body is steel. The primary point is to supplant the body material steel with various steel amalgam (ASTM A710, ASTM A4130, MILD STEEL and STEEL ST 52) body materials. By utilizing steel, the heaviness of the case is more contrasted and steel compound (ASTM A710, ASTM A4130, MILD STEEL and STEEL ST 52) undercarriage. Crash investigation, Structural and irregular vibration examination is done on the body models 'C' segment and rectangular box segment. Crash investigation to decide the pressure, disfigurement and strain while applying abrupt burden on the part. Static investigation to decide the twisting, proportionate anxiety to finding the quality of the segment when segment is in rest position. Modular investigation to decide the directional distortion, shear pressure and shear strain to discover the vibrations of undercarriage. 3D demonstrating in CREO and investigation in ANSYS programming.

A Clutch is a machine member used to connect the driving shaft to a driven shaft, so that the driven shaft may be started or stopped at will, without stopping the driving shaft. A clutch thus provides an interruptible connection between two rotating shafts.
