Impact of the Shodan Computer Search Engine on Internet-facing Industrial Control System Devices

Abstract : The Shodan computer search engine crawls the Internet attempting to identify any connected device. Using Shodan, researchers identified thousands of Internet-facing devices associated with industrial controls systems (ICS). This research examines the impact of Shodan on ICS security, evaluating Shodan's ability to identify Internet-connected ICS devices and assess if targeted attacks occur as a result of Shodan identification. In addition, this research evaluates the ability to limit device exposure to Shodan through service banner manipulation. Shodan's impact was evaluated by deploying four high-interaction, unsolicited honeypots over a 55 day period, each configured to represent Allen-Bradley programmable logic controllers (PLC). All four honeypots were successfully indexed and identifiable via the Shodan web interface in less than 19 days. Despite being indexed, there was no increased network activity or targeted ICS attacks. Although results indicate Shodan is an effective reconnaissance tool, results contrast claims of its use to broadly identify and target Internet-facing ICS devices. Additionally, the service banner for two PLCs were modified to evaluate the impact on Shodan indexing capabilities. Findings demonstrated service banner manipulation successfully limited device exposure from Shodan queries.
Development and Evaluation of a Video Designed to Enhance Officer Career Continuance

Abstract : The purpose of this research was to develop and evaluate an intervention designed to improve U.S. Army company grade officer career continuance. This intervention was a video featuring interviews with former officers to present their perspective on what aspects of the Army they miss in civilian life. We conducted focus groups with 155 current company grade officers to evaluate the ability of the video to influence career decisions and intentions toward staying in the Army. Between 15-29% of participants agreed with various post-viewing survey questions about the video changing different attitudes they had about the Army (e.g., appreciate aspects of being an officer that were taken for granted, more convinced they made the right choice by joining the Army), and over 45% said that the video helped clarify for them the unique benefits of being an officer. There was some degree of consensus from different sources that if the video was shown to officers who were at a decision point, if the showing of the video was accompanied by counseling by one's commander, and if the video was also shown to the spouse as a stimulus of much-needed conversation, that it could prove to be well worthwhile and possibly advantageous in retaining company grade officers.
Sawing SHOLO logs: three methods

Three different methods of sawing the SHOLO log were compared on a board-foot yield basis. Using sawmill simulation, all three methods of sawing were performed on the same sample of logs, eliminating differences due to sapling. A statistical test was made to determine whether or not there were any real differences between the board-foot yields. Two of the sawing methods provided about the same board-foot yields; one provided about 40 percent less.
Scan and Z-Curve Trajectory for Mobile Anchor in Localization of Wireless Sensor Network

In the recent decades, Wireless Sensor Networks has become an inevitable and dependable research area in the field of communication. Sensor Networks is an apt application for the complicated and instant communication fields like the surveillance in the military services, monitoring of medical analysis and research, detecting forest fire break outs, and detection of acoustics. For an effective application of sensor networks, the research issue shall be laid on the path planning. By path planning it is meant the path through which the mobile beacon should travel without any interruption by enhancing the accuracy in localization process. Of late Global Positioning System (GPS) has become a reliable means for its precision in sensor localization. However, GPS does not provide cost-efficiency or energy-efficiency. As a result, single GPS could be positioned along the travel path. To optimize this constraint, in this paper, an attempt is made to derive the performances of two path planning techniques namely Z-curve and SCAN. It is known that in sensor localizing and for broadcasting of data, the mobile beacon is determined to travel in both directions, viz forward and backward. Comparison is made between the Z-curve trajectory positioned with mobile beacon and SCAN trajectory affixed with mobile beacon having a path planning scheme. The comparison results showed that Z-curve method yielded better performance in terms of high precision and short duration for localization. Further, Z-curve produced only minimum localization error.
Comparing Three Building Life Cycle Assessment Tools for the Canadian Construction Industry

This research aims to contribute to quantifying whole building life cycle assessment using various software tools to determine how they can aid the construction industry in reducing carbon emissions, and in particular embodied emissions, through analysis and reporting. The conducted research seeks to examine and compare three whole building life cycle assessment tools; Athena Impact Estimator, Tally and One-Click LCA to relate the input variability to the outputs of the three programs. The three whole building life-cycle assessments were conducted using a case study building with an identical bill of materials and compared to determine the applicability and strengths of one program over another. The research confirmed that the three programs output significantly different results given the variability in scope, allowable program inputs and generated “black-box” back-end calculations, where the outputted whole building life cycle carbon equivalents of One-Click LCA is less than half than of Tally meaning the programs outputs cannot be simply compared side-by-side.
Kleemenko cycle coolers : Low cost refrigeration at cryogenic temperatures

Low-cost refrigerators that use a single stream, throttle expansion cycle of a mixture of refrigerants have recently been developed for operation between 65 K and 150 K These have proved to be exceptionally reliable and comparable in efficiency with Stirling and Gifford-McMahon cryocoolers. They are finding use in many applications where cost is a controlling factor. These include coolers for cryo-acceleration of workstations, for biomedical storage, low noise amplifiers for communication equipment, x-ray detectors and for cryosurgical devices. We give a brief history of this development and address those issues that could lead to still wider application of these coolers.
Investigation of instantaneous hydrodynamics and heat transfer to a horizontal tube immersed in a high-temperature gas-solid fluidized bed of large particles

approved: Experimental results are presented related to the hydrodynamic and heat transfer behavior between a high-temperature, bubbling, gas-solid fluidized bed of large particles and an immersed horizontal tube. A methodology has been developed to interpret signals from optical probes inserted in a bed which was validated by comparing experimental results to video-tape of a two-dimensional bed (2D). The optical probe signals (voltages) were filtered to calculate bubble (or emulsion) frequency, bubble velocity, pierced length, characteristic bubble size, bubble (or emulsion) residence time, and bubble (or emulsion) residence time fraction. A fast-response heat flux sensor suitable for the high-temperature, abrasive bed environment was built and mounted on the outside of a 51 mm outside diameter tube. Experiments were performed with the optical probes and instantaneous heat flux sensor in Redacted for privacy a three-dimensional (3D) bed at temperatures ranging from 600 K to 1000 K, over a range of fluidization velocities, with 2.0 mm and 2.9 mm refractory particles. Instantaneous heat transfer information was collected at circumferential intervals on the tube of 45°. Bubble phase and emulsion phase properties and heat transfer coefficients were determined and their dependence on bed temperature, fluidization velocity and particle size were established. Existing correlations for the prediction of timeand space-averaged heat transfer coefficients were evaluated. From these, new relations are presented to correlate local emulsion and bubble phase heat transfer coefficients. These expressions are 0.133 Num = 8.95 (1 60)) + 0.16 Ar " Re °I,5mf Pr 113 (1 e(°)) E (0) 0'8 for the emulsion phase, and Nup,b = D, 0.73 . 1%l. mf Re" for the bubble phase. These correlations each predicted heat transfer coefficients for the conditions in the present work within ±15%. They apply to the range of conditions investigated in the present work: 44,000 < Ar < 136,000; 27 < Remf < 57; 39 < Re < 72; and 6.8 < Pr < 7.0.

A Comprehensive Social Matrix Factorization with Social Regularization for Recommendation Based on Implicit Similarity by Fusing Trust Relationships and Social Tags

Social relationships play an important role in improving the quality of recommender systems (RSs). A large number of experimental results show that social relationship-based recommendation methods alleviate the problems of data sparseness and cold start in RSs to some extent. However, since the social relationships between users are extremely sparse and complex, and it is difficult to obtain accurately user preference model, thus the performance of the recommendation system is affected by the existing social recommendation methods. In order to accurately model social relationships and improve recommendation quality, we use explicit social relationships such as user-item ratings, trust relationships and implicit social relationships such as social tags to mine potential interest preferences of users and propose an improved social recommendation method integrating trust relationship and social tags. The method map user features and item features to the shared feature space by using the above social relationship, respectively, and obtains user similarity and item similarity through potential feature vectors of users and items, and continuously trains them to obtain accurate similarity relationship to improve the recommendation performance. Experimental results demonstrate that our proposed approach achieves superior performance to the other social recommendation approaches.

Decomposition of inequalities in Poland (of incomes, expenditures, and their difference), which includes the overlapping-due term, is performed and analysed.
Plant Oil/Fusel Oil Blends as Alternative Fuels in Low- and Medium Speed Diesel Engines

Fuel blending is one of the methods of lowering plant oil’s viscosity, which is the major parameter that leads to serious problems on diesel engine performance in terms of operation and durability. A study was carried out on fuel properties of Jatropha (JO) and Croton (CROT) seed oils blended with a distillery by-product, fusel oil (FO) (modifier) of between 20% and 50% (v/v) at room temperature (30 ± 3˚C). The effect of FO composition in the resulting blend on the kinematic viscosity and fuel combustion properties of the blends was analysed. The results were compared to the properties of crude plant oils (POs) and diesel fuel (grade-4D) specifications. The blends were found to be compatible over a wide range of compositions and exhibited much lower viscosity and better combustion properties than crude plant oil (PO) samples. The optimum proportions for a blend’s viscosity to meet the specifications for diesel fuel (grade 4-D) were found to depend on the modifier characteristics; and that 20% (v/v) FO was enough to produce the desired liquid biofuel blend. The characteristics of blends presented in this work matches well with the characteristics of fuels for low- and medium-speed diesel engines. This implies that the PO/FO blends can be used as alternative fuels in low- and medium speed diesel engines.
Development of Radar Pulse Compression Techniques UsingComputational Intelligence Tools

Pulse compression techniques are used in radar systems to avail the benefits of large range detection capability of long duration pulse and high range resolution capability of short duration pulse. In these techniques a long duration pulse is used which is either phase or frequency modulated before transmission and the received signal is passed through a filter to accumulate the energy into a short pulse. Usually, a matched filter is used for pulse compression to achieve high signal-to-noise ratio (SNR). However, the matched filter output i.e. autocorrelation function (ACF) of a modulated signal is associated with range sidelobes along with the mainlobe. These sidelobes are unwanted outputs from the pulse compression filter and may mask a weaker target which is present nearer to a stronger target. Hence, these sidelobes affect the performance of the radar detection system. In this thesis, few investigations have been made to reduce the range sidelobes using computational intelligence techniques so as to improve the performance of radar detection system. In phase coded signals a long pulse is divided into a number of sub pulses each of which is assigned with a phase value. The phase assignment should be such that the ACF of the phase coded signal attain lower sidelobes. A multiobjective evolutionary approach is proposed to assign the phase values in the biphase code so as to achieve low sidelobes. Basically, for a particular length of code mismatch filter is preferred over matched filter to get better peak to sidelobe ratio (PSR). Recurrent neural network (RNN) and recurrent radial basis function (RRBF) structures are proposed as mismatch filters to achieve better PSR values under various noise conditions, Doppler shift and multiple target environment.
