This article analyses the history and current state in the area of outdoor protection. In the first part of the article, the sensory systems, which have been used for many years are described. Attention is paid to the sensors using conventional principles of the detection of the objects. New modern sensory systems together with their principles used for the protection of the outdoor environment are also described. Other problem is that older sensory systems of spatial protection were focused on the security of properties and buildings without expecting any change position in the time. The article analyzes also new possibilities of protecting of the outdoor perimeter even in the situations when the borders of the areas of interest are only temporary or mobile. And as UAV systems have been used massively and often involve modern multisensory systems, the last part of the article describes current sensors, which have been currently used to detect the UAV systems and to to protect the area of interest.

Interest In Research

- There has been an increased interest in research on paranoia and persecutory delusions. This is partly based on the idea that paranoia exists on a continuum ranging from sub-clinical to clinical levels. One area of interest is in social cognition as it may provide methods to understand how persons with paranoia perceive, interpret, and understand their social world. Previous research has showed that social cognition directly influences or mediates social functioning. Paranoia can be ideally approached from a social cognitive perspective, which makes understanding these processes even more important. For this review, we will focus on the current state of knowledge for paranoia as it pertains to the three primary domains of social cognition: 1) emotion/social perception, 2) theory of mind, and 3) attributional style. Deficits in emotion/social perception appear to be found across the paranoia continuum. In contrast, deficits in theory of mind and attributional style are typically found in persons with clinical levels of paranoia. Future studies should focus on understanding the processes that might underlie the deficits.

The Right

The main area of interest of this paper focuses on the right to strike in public education sector. All the possibilities of limiting the right to strike in this public sector needs to be verified in the context of constitutional provisions and international legal obligations binding the legislator. The possibility of “including” teachers in the Civil Service Corps is being considered in this paper. Under the current state of law, there are no grounds to restrict or prohibit the right to strike in the education sector. The potential subordination of teachers to the rigours binding the Civil Service Corps would require far-reaching adjustments within this institution, stemming from the constitutional provisions that would necessitate these changes.

The methods for autonomous navigation of a robot in a real world environment is an area of interest for current researchers. Although there have been a variety of models developed, there are problems with regards to the integration of sensors for navigation in an outdoor environment like moving obstacles, sensor and component accuracy. This paper details an attempt to develop an autonomous robot prototype using only ultrasonic sensors for sensing the environment and GPS/ GSM and a digital compass for position and localization. An algorithm for the navigation based on reactive behaviour is presented. Once the robot has navigated to its final location based on remote access by the owner, it surveys the geographical region and uploads the real time images to the owner using an API that is developed for the Raspberry PI’s kernel.

There is a growing interest in minimizing the energy and cost associated with desalination. To do this, various new desalination systems and approaches are being explored. One growing area of interest revolves around electrochemical separations for deionization. Electrochemical separations primarily consist of technologies which either intercalate or electroadorb species of interest from a bulk mixture. This can be conducted through polarizing a battery electrode, or more commonly a capacitive electrode. One example is the technology capacitive deionization (CDI). CDI is being investigated as a means to augment the current state of the art, and as a stand-alone brackish water treatment technology. Despite the potential of this technology, there is still much that is not known regarding the energetics and efficiency of both the desalination and brine formation process. Here, blue refrigeration is a term used to broadly describe desalination cycles and processes. The analogy aims to compare the energetics associated with a desalination cycle to the energetics well studied in thermal refrigeration cycles. This perspective aims to evaluate some of the emerging energetic issues associated with CDI, and to describe how new system architectures may play a role in achieving more ideal energy and desalination performance.

Internet is one of the main components of the information superhighway. By accessing information on networks, we as professionals can add to the information stream and disseminate research data and academic applications in a timely manner. Users worldwide can use this data to add to their ongoing research efforts. Both binary and ASCII files can be transmitted. One of the main obstacles new users must face is locating the proper area of interest. The use of FTP (File Transfer Protocol) allows users to transfer data between their server and other servers on Internet. For help in finding areas of interest there are two common systems being used. One is called Archie and allows the searching of Archie servers with key words. Substring searches can be used if you do not know the exact name of a resource. Another system is called Gopher and is menu driven. Gopher provides an easier way to search for the information you are looking for, since it allows users to move within modular menu components. LISTSERV, a mail manager system, allows the distribution of information by mailing lists in less time than regular Internet mail programs, further adding to the system efficiency.

Abstract. The Geomatics Division of the Centre Tecnològic de Telecomunicacions de Catalunya (CTTC) has been producing terrain displacement maps for more than 15 years using the PSIG software chain, developed entirely by the members of the aforesaid group. PSIG has reached a high level of maturity, being highly automated but also offering the user the possibility to fine-tune the set of critical parameters controlling the process. However, large areas with a high level of diversity often pose problems in finding a good quality solution using a single set of parameters. Improving the quality of the final terrain displacement map means being able to process very local and critical areas using specific sets of parameters; however, identifying such areas is a difficult process without suitable analysis tools. The VETools, a new software project still under development, but very close to its completion, target this problem. With the VETools it is possible to visualize the results produced by a previous PSIG global processing, analysing their quality, thus making possible to identify the local, critical areas, allowing the user to interactively experiment with specific sets of parameters for these areas, reprocessing them and reviewing the local results as many times as desired and, finally, merging all of them in a single, unique solution whose level of quality is appropriate for the whole area of interest. This work presents the current state of development of the VETools, describing their features and the challenges overcome.

This paper details the procedures necessary to accurately determine the stress in the bolts on a coke gasifier inlet flange using current state-of-the-art practices. Using accepted ASME Code practices (ASME [1]), the stress results are then used to justify the elimination of the spacers that were specified in the original design. Computational fluid dynamics (CFD) is employed to determine heat transfer coefficient distributions in the areas of interest. Finite element (FE) analysis is used to compute the transient assembly temperatures and related bolt stresses. By evaluating the bolt stresses as specified in ASME Div. 1 [1], these analyses were used to determine that the spacers could safely be eliminated during operation.

Areas Of Interest

The localization of an area of interest for ultramicrotomy within a tissue block is usually determined by first surveying large thick sections under the light microscope. Yang has shown that multiple areas from a large block face can be vertically divided for sequential sectioning. By applying a simple and direct technique, two or more areas of interest from the same block can be sectioned simultaneously and examined on one grid for ultrastructural studies.Depending on the size and distance between the areas that are going to be sectioned, there are several possible approaches:1.Two Small Areas Widely Separated. Since the entire surface of the block is in one plane after thick sectioning, it is possible to rotate the block and trim selected areas into two trapezoids so that their leading and trailing edges are parallel to the knife edge. If their combined total areas do no exceed the average area routinely sectioned, the two trapezoids can be cut simultaneously and two ribbons formed (fig.1).

Abstract Failure analysis laser inspection tool (FA/LIT) is a tool for the analysis of packaged devices. FA/LIT can routinely expose bond wires for inspection; however, concerns develop for the exposure of stitch bonds, the examination of small trace cracks, and any requirements to maintain electrical functionality of devices. Matching the FA/LIT settings based upon operation and sample material is critical in achieving good exposure of areas of interest with minimal damage. The use of practice samples, or areas away from the area of interest, to verify results before operations on actual FA parts is strongly recommended in this article. The installation of a grounded sample holder has been shown to greatly improve electrical integrity of samples during the laser ablation procedure. Use of the grounding sample holder improved electrical test results from 0% pass to 100% pass in advanced CMOS devices.

Interface Materials

The reduction of interfacial resistance continues to be a significant challenge in thermal management of semiconductor and other microscale devices. Current state-of-the-art thermal interface materials (TIMs) have resistances in the range of 5–10 mm2·K/W. At these values, particularly for the emerging highly nonhomogeneous materials, standard measurement techniques often fail to provide accurate results. This paper describes the use of infrared microscopy for measuring the total thermal resistance across multiple interfaces. The method is capable of measuring samples of wide ranging resistances with thicknesses ranging from 50–250 μm. This steady-state technique has several advantages over other methods, including the elimination of the need for intrusive temperature monitoring devices like thermocouples at the area of interest and the need for a priori knowledge of the specific heat and density of the materials of interest, as in the transient techniques for determining thermal resistances. Results for three different commercially available TIM and uncertainty analysis are presented.
