Finding Out How Close Source Code Files Are To Files In The Git Version Control System., Armijn Hemel

Defensive Publications Series

A lot of popular software is developed using a version control system. Historically systems such as RCS, CVS and Subversion were used, but a lot of developers have moved to Git. These systems have a lot of information available about the history of a file. When software is distributed, it is often distributed without this history information. In some situations it is important to find out how close a certain piece of software is to any given version in a version control system, for example for assessing copyright, security research or other provenance issues.

Optimized Decision Making In The Power Industry Using Machine Learning, Yixin Wang, Xin Li

Defensive Publications Series

To supply power to customers, a power company procures fuel from suppliers while also holding an inventory of such fuel and/or storing a very limited amount of excess power in a battery. Additionally, a power company may directly sell renewable energy sources to customers and exchange power with a neighboring grid to ameliorate shortages. The standard techniques of optimizing profit entail a tedious, human-driven decision-making procedure that results only in local optima. This disclosure optimizes the profit of a power company by automatically making intelligent procurement and selling decisions using machine learning. The decisions are treated as an end-to-end supply-chain …

Use Of Machine Learning To Generate Estimates Of Code Review Time And Effort, Marko Ivanković, Goran Petrovic

Defensive Publications Series

Providing accurate estimates of time required to perform code reviews can enable practitioners to prioritize reviews and can help improve productivity. Currently, factors such as the number of lines of code to be reviewed, or the number of code files, are provided to the reviewer.

Identification Of Low-Value Code To Improve Efficiency Of Automated Code Analysis, Marko Ivanković, Goran Petrovic

Defensive Publications Series

Certain software testing techniques such as mutation testing are often not utilized due to the relatively high proportion of testing activity that is not deemed useful. Such techniques can benefit from identification of high-value code. This disclosure describes the classification of different parts of a codebase into high and low value code. The techniques utilize an abstract syntax tree (AST) generated from the codebase on which predefined heuristics are applied to identify low-value code. A propagation algorithm is applied to mark low value branches. Additionally, machine learning techniques are applied to classify portions of code as high or low value. …

Secure Communication Using Deterministic Key Rotation Over Elliptic Curves, Ismail Turk

Defensive Publications Series

This disclosure describes techniques for using deterministic key rotation in encryption to secure communication of data between clients in a server-client configuration. A unique encryption key is generated by a client for each client message without exchanging the key between clients. The server can translate a message encryption key from one client to a form usable by other clients and send the encrypted message to other clients without performing re-encryption. Described techniques reduce per-message cryptographic load on a server while maintaining communication security, integrity, and privacy.

Application Of Ultrafast And Co2 Lasers For Cutting Waveguides, Moez Haque, Saeid Rezaei, Victor Isbrucker

Defensive Publications Series

Techniques for the cutting of waveguides from patterned glass wafers are described. Translation of an ultrafast laser beam across a wafer is performed to mark the wafer by forming a filament curtain that is aligned to the waveguide edge profile. Chucks are used to secure the wafer during marking and subsequent separation of the waveguides. The chucks include vacuum ports placed at selected locations for debris control around the cut edges. After marking, thermal shock is induced by CO2 laser absorption for breakage along the filament curtain and waveguide separation (singulation). An optical imaging system is used to calibrate the …

Impurity-Impurity Interaction In Silicon Doped With Manganese And Nickel, Sh. Utamuradova, Sh. Yusupova, K. Fayzullaev

Euroasian Journal of Semiconductors Science and Engineering

Using the radioactive technique and capacitive spectroscopy, it was found that the doping of Si with manganese from the layer on the surface leads to a decrease in both the total concentration of Ni and the concentration of electroactive Ni atoms. The Mn layer deposited on the Si surface acts as a getter for the Ni impurity. It is shown that with successive doping of Ni and then Mn, and simultaneous doping of silicon with Mn and Ni, only the levels characteristic of Mn are observed.

Some Thermoelectric Properties Of Heteroepitaxial Structures Of Si-Ge / Si Doped With Titanium, Sh. Kuchkanov, Kh. Ashurov, B. Abdurahmanov

Euroasian Journal of Semiconductors Science and Engineering

The current flow and the appearance of thermoelectric power on uniformly heated p-n structures containing films heavily doped with titanium on the Si-Ge surface were detected under the conditions of a “thermal bath”. The results are discussed from the standpoint of the manifestation of the thermovoltaic effect, that is, the generation of charge carriers due to the absorption of subband photons with the participation of deep energy levels due to both defects in Si-Ge films and an admixture of titanium.

Euroasian Journal of Semiconductors Science and Engineering

The recombination rate of non-equilibrium carriers is calculated for a semiconductor model with a pair recombination complex, the activity of which decreases during excitation. It is shown that the dependence of the electron capture coefficient on the first level on the filling of the second level leads to a decrease in the recombination rate.

Tenzostimulated Current Relaxation In Surface-Barrier Diode Structures, O. Mamatkarimov, O. Khimmatkulov, I. Tursunov

Euroasian Journal of Semiconductors Science and Engineering

The effect of pulsed external all-round pressure on the I–V characteristics of surface-barrier diode structures is investigated. It is shown that under the adiabatic regime of exposure to HCV, the generated heat leads to short-term heating of the diode, as a result of which current relaxation is observed, which correlates with a change in temperature. The contribution of temperature to the change in current decreases with increasing applied forward voltage.
