Digital Evidence In Appeals Of Criminal Cases Before The U.S. Courts Of Appeal: A Review Of Decisions And Examination Of The Legal Landscape From 2016 – 2020

This study is a follow-up to Digital Evidence in Criminal Cases before the U.S. Courts of Appeal: Trends and Issues for Consideration – 2010 to 2015. The current study examines appeals of criminal cases before the United States Courts of Appeal from January 2016 through August 2020, where one or more appeal claims were related to digital evidence. The purpose of this research was to determine if the legal landscape has changed since 2015; examine the most relevant legal issues related to digital evidence; and analyze how precedential cases may have affected digital forensics as evidence

Digital Evidence in Criminal Cases Before the U.S. Courts of Appeal: Trends and Issues for Consideration

Though the use of computer forensics in criminal investigations has expanded in recent years, there is little empirical evidence about the prevalence of the use of digital evidence in the court system and its impact on prosecution outcomes. This paper was an examination of criminal cases before the United States Courts of Appeal in which legal issues were related to digital evidence. The purpose of this research was to determine the most common legal basis for appeals relating to the introduction or exclusion of digital evidence, the frequency with which cases involving an appeal regarding digital evidence affirmed or reversed for the defense, whether certain challenges to digital evidence are more prevalent than others, and whether there are trends or areas of the law as applied to computer forensics and digital evidence needing further attention by the criminal justice system

Проблемы качества поверхности закаленных сталей при динамических нагружениях

Стаття присвячена проблемам зміни поверхневої цілісності компонентів загартованих сталей. Основою експерименту є підготовка зразків із загартованої сталі шляхом шліфування її при різних умовах різання, оцінки значень поверхневої цілісністності внаслідок динамічних навантажень в умовах різного оточующого середовища. Зміни поверхневої цілісності спостерігаються в залежності від кількості циклів динамічного навантаження та типу оточующого середовища, у якому відбувалось навантаження.This article deals with problems of changes of surface integrity components of ground hardened steels. Experiment fundamentals is samples preparation from hardened steel material by grinding at different cutting conditions, evaluation of origin values of surface integrity components and subsequently dynamic load in different surrounding. Changes of surface integrity components are monitoring in depending on dynamic load cycles count and kind of surrounding, in which to the load happened. Quality of surface and surface layer is dependence on cutting conditions a subsequently on surrounding in which will the components work. Evaluation of quality surface and product manufacture qualities are determinants factors for objective and correctly appreciation proprieties of components. From this experiment deduce conclusion, that aggressive surrounding isn’t always unprofitable for material. This experiment showed, that in evaluation of quality surface and surface layer due to roughness, roundness and residual stress achieving same values while using oil supply in corrosion surrounding as while dynamic load in normal surrounding.Данная статья посвящена проблемам изменения поверхностной целостности компонентов закаленных сталей.

Development of Urban Electric Bus Drivetrain

The development of the drivetrain for a new series of urban electric buses is presented in the paper. The traction and design properties of several drive variants are compared. The efficiency of the drive was tested using simulation calculations of the vehicle rides based on data from real bus lines in Prague. The results of the design work and simulation calculations are presented in the paper

Density games

The basic idea of evolutionary game theory is that payoff determines reproductive rate. Successful individuals have a higher payoff and produce more offspring. But in evolutionary and ecological situations there is not only reproductive rate but also carrying capacity. Individuals may differ in their exposure to density limiting effects. Here we explore an alternative approach to evolutionary game theory by assuming that the payoff from the game determines the carrying capacity of individual phenotypes. Successful strategies are less affected by density limitation (crowding) and reach higher equilibrium abundance. We demonstrate similarities and differences between our framework and the standard replicator equation. Our equation is defined on the positive orthant, instead of the simplex, but has the same equilibrium points as the replicator equation. Linear stability analysis produces the classical conditions for asymptotic stability of pure strategies, but the stability properties of internal equilibria can differ in the two frameworks. For example, in a two-strategy game with an internal equilibrium that is always stable under the replicator equation, the corresponding equilibrium can be unstable in the new framework resulting in a limit cycle

The Removal of Artificially Generated Polarization in SHARP Maps

We characterize the problem of artificial polarization for the Submillimeter High Angular Resolution Polarimeter (SHARP) through the use of simulated data and observations made at the Caltech Submillimeter Observatory (CSO). These erroneous, artificial polarization signals are introduced into the data through misalignments in the bolometer sub-arrays plus pointing drifts present during the data-taking procedure. An algorithm is outlined here to address this problem and correct for it, provided that one can measure the degree of the sub-array misalignments and telescope pointing drifts. Tests involving simulated sources of Gaussian intensity profile indicate that the level of introduced artificial polarization is highly dependent upon the angular size of the source. Despite this, the correction algorithm is effective at removing up to 60% of the artificial polarization during these tests. The analysis of Jupiter data taken in January 2006 and February 2007 indicates a mean polarization of 1.44%+/-0.04% and 0.95%+/-0.09%, respectively. The application of the correction algorithm yields mean reductions in the polarization of approximately 0.15% and 0.03% for the 2006 and 2007 data sets, respectively.Comment: 19 pages, 7 figure

Human Hand Anatomy-Based Prosthetic Hand

[EN] The present paper describes the development of a prosthetic hand based on human hand anatomy. The hand phalanges are printed with 3D printing with Polylactic Acid material. One of the main contributions is the investigation on the prosthetic hand joins; the proposed design enables one to create personalized joins that provide the prosthetic hand a high level of movement by increasing the degrees of freedom of the fingers. Moreover, the driven wire tendons show a progressive grasping movement, being the friction of the tendons with the phalanges very low. Another important point is the use of force sensitive resistors (FSR) for simulating the hand touch pressure. These are used for the grasping stop simulating touch pressure of the fingers. Surface Electromyogram (EMG) sensors allow the user to control the prosthetic hand-grasping start. Their use may provide the prosthetic hand the possibility of the classification of the hand movements. The practical results included in the paper prove the importance of the soft joins for the object manipulation and to get adapted to the object surface. Finally, the force sensitive sensors allow the prosthesis to actuate more naturally by adding conditions and classifications to the Electromyogram sensoDunai, L.; Novak, M.; Garcia Espert, C. (2021).
