Opis:
The identification of isometric displacements of studied objects with utilization of the vector product is the aim of the analysis conducted in this paper. Isometric transformations involve translation and rotation. The behaviour of distances between check points on the object in the first and second measurements is a necessary condition for the determination of such displacements. For every three check points about the measured coordinate, one can determine the vector orthogonal to the two neighbouring sides of the triangle that are treated as vectors, using the definition of the vector product in three-dimensional space. If vectors for these points in the first and second measurements are parallel to the studied object has not changed its position or experienced translation. If the termini of vectors formed from vector products treated as the vectors are orthogonal to certain axis, then the object has experienced rotation. The determination of planes symmetric to these vectors allows the axis of rotation of the object and the angle of rotation to be found. The changes of the value of the angle between the normal vectors obtained from the first and second measurements, by exclusion of the isometric transformation, are connected to the size of the changes of the coordinates of check points, that is, deformation of the object. This paper focuses mainly on the description of the procedure for determining the translation and rotation. The main attention was paid to the rotation, due to the new and unusual way in which it is determined. Mean errors of the determined parameters are often treated briefly, and this subject requires separate consideration.

Opis:
This article examines the Internet’s emergent role in the claims-making process. My central premise is while Internet technology provides lay citizens with a mass mediated platform to distribute claims publically, power dynamics in the public sphere have remained relatively stable: Insiders and lobbyists continue to be powerful cultural voices; the press still functions as a cultural gatekeeper of newsworthiness; most people continue to have relatively little social authority; and the least powerful risk being completely left out of a digital society. Using the National Rifle Association (NRA) web presence as a case study, I describe the Internet as a vast collection of interconnected public cyber-arenas where problem claims are continuously disseminated, global communication is facilitated via online advocacy networks, and claimants utilize novel cyber-strategies to mobilize supporters. In doing so, I examine how cyber-arenas fundamentally differ from more static traditional claims-making arenas like television, radio, and print publication. I conclude by considering the extent to which historically powerful insider claims-making groups like the NRA are actually best positioned to succeed in a supposedly democratized new media world.

The influence of the particle size on the surface sensitivity in XPS analysis was investigated. Previous reports about such influence were qualitatively only. In this report there are given mathematical description of XPS sensitivity and quantitative results. It was found that influence due to nanometric size on XPS analysis can be noticeable for particles below 15 nm of diameter and increases dramatically with reduction of the size.

Opis:
The pyrokinin (PK) family plays a multifunctional role in an array of important physiological processes in a variety of insects. A PK active core analog containing an (E)-alkene, transPro isosteric component was evaluated in five disparate PK bioassays and/or in a recombinant PK receptor cell line, representing six different insect species. The assays included pheromone biosynthesis in the moth Heliothis peltigera, melanization in the larval Spodoptera littoralis, pupariation acceleration in the larval fly Neobellieria bullata, diapause termination in the moth Heliothis zea, and hindgut contraction in the cockroach Leucophaea maderae. This constrained analog demonstrated unselective agonist activity that approached, matched, or exceeded the activity of parent PK peptides of equal length in all six PK assays. The results provide strong evidence for the orientation of Pro and the core conformation adopted by PK neuropeptides during interaction with disparate PK receptors. A PK active core analog incorporating a second transPro motif, the dihydroimidazoline moiety, was found to demonstrate pure, selective agonism in the melanotropic bioassay, with no significant activity in three other PK bioassays. Both types of transPro isosteric analogs feature modification adjacent to the primary tissue-bound peptidase hydrolysis site that is expected to enhance biostability over natural PK peptides. The research further identifies two novel scaffolds with which to design either selective or non-selective mimetic PK analogs as potential leads in the development of environmentally favorable pest management agents capable of disrupting PK-regulated systems.

Opis:
The local chemical properties of bimetallic surfaces, which are often drastically different from those of each of the components, will be discussed. Using CO adsorption as a probe molecule it will be shown for two model systems, Au/Pd(111) and Pt/Ru(0001), that their chemical properties depend decisively on the local surface structure and that the correct interpretation of area integrating spectroscopic and kinetic data obtained from such surfaces requires detailed knowledge of their (defect) structure and of the distribution of the different components in the surface layer. It will further be shown that information on the local chemical properties of specific structural elements such as monolayer islands and monolayer island edges, and specific surface ensembles can be gained by applying high resolution scanning tunneling microscopy imaging and area integrating spectroscopic techniques in combination to bimetallic surfaces whose morphology and composition is varied in a systematic and controlled way. Based on experimental results adsorption on a monolayer A / substrate B system is suggested as a model for gaining information on the modifications in chemical properties of AB alloy surfaces due to metal-metal interactions.

This paper shows effective method of linear distortions compensation in zero-IF receivers. With application of frequency domain processing a computation efficient method was developed that allows to correct quadrature mismatch in Zero-IF receiver along with gain and group delay independent of receiving signal type. Method was implemented and tested on hardware platform confirming its effectiveness. This method makes it possible to build high sensitivity devices to monitor spectrum in very wide frequency ranges.

Opis:
Enhanced Traffic Management System (ETMS) stores all the information gathered by the Federal Aviation Administration (FAA) from aircraft flying in the US airspace. The data stored from each flight includes the 4D trajectory (latitude, longitude, altitude and timestamp), radar data and flight plan information. Unfortunately, there is a data quality problem in the vertical channel and the altitude component of the trajectories contains some isolated samples in which a wrong value was stored. Overall, the data is generally accurate and it was found that only 0.3% of the altitude values were incorrect, however the impact of these erroneous data in some analyses could be important, motivating the development of a filtering procedure. The approach developed for filtering ETMS altitude data includes some specific algorithms for problems found in this particular dataset, and a novel filter to correct isolated bad samples (named Despeckle filter). As a result, all altitude errors were eliminated in 99.7% of the flights affected by noise, while preserving the original values of the samples without bad data. The algorithm presented in this paper attains better results than standard filters such as the median filter, and it could be applied to any signal affected by noise in the form of spikes.
