Comprehension and Utilization of Core Assets Models in Software Product Line Engineering

In software product line engineering, core assets are reusable artifacts that are intended to be used by a family of software products in order to improve development productivity and quality of particular software products. In order to support the construction and maintenance of core assets, various modeling methods have been proposed. However, the assessment of these methods is still in an incubation stage. In fact, only several frameworks for comparing and evaluating these methods have been suggested. These mainly refer to lists of criteria whose examination is sometimes subjective and opinion-dependent. In this paper, we call for empirical evaluation of the comprehension and utilization of core assets and report the initial results of a series of studies we performed in this context.
Towards hardware embedded virtualization technology: architectural enhancements to an ARM SoC

Embedded virtualization possesses inherent challenges which differentiate the domain from traditional virtualization application fields such as server and desktop computing. Standard software virtualization solutions have a negative impact, not only on memory footprint and performance, but also on determinism and interrupt latency which are critical for the embedded real-time domain. Thus, efficient embedded virtualization requires domain-specific software and hardware support. This paper presents work in progress results of hardware-based Hypervisor implementation. The use cases of embedded virtualization are analyzed, justifying the reasoning for hardware-supported virtualization. Architectural and micro-architectural improvements to an ARM v5TE processor are described, demonstrating the performance advantages, and compared against ARM Virtualization Extensions, identifying respective vulnerabilities and providing alternative solutions which enable higher flexibility, minimizing virtualization costs. The research roadmap towards a hardware-complete Hypervisor, based on the presented results, is described.
3D head texture using multiple kinect

Texture for 3D models is one important component of computer graphics. In this paper, we propose a method for generating a coherent, integrated and seamless texture on 3D head models. In the process, the color images and depth data captured by Kinect are established a correspondence to build initial texture on the head surface. Then the visible mismatching seams in the adjacent texture regions are effectively removed by an iterative coarse-to-fine strategy, resulting in an accurate aligned texture. In the following, the illumination variations among different color images are eliminated by color fusion in gradient domains. Finally, one texture is generated for the whole 3D head model by non-texture repair. The experiments demonstrate that the coherent and seamless texture method for 3D head is effective and robust.
Fairness evaluation of practical spectrum sharing techniques in LTE networks

In the context of dynamic spectrum access, spectrum sharing among multiple operators has recently emerged as a promising paradigm to improve the efficiency of resource usage. Several theoretical evaluations have proven the benefits offered by pooling the available frequencies so as to tune the capacity offered by the operators according to their different needs, especially the service demands from their users. However, practical aspects concerning the application of sharing techniques are rarely studied, and deserve more detailed investigations. This paper aims at tackling this problem, in particular investigating the impact of asymmetries and dynamics of the user demands on the implementation of spectrum sharing techniques and the resulting performance, especially in terms of fairness among the users, which seems to be often neglected by many studies. We show that in variable traffic conditions, a constantly monitored and updated sharing of frequency bands performs much better than a static allocation simply based on average traffic loads. However, it is possible to choose the update rate of the spectrum allocation so that it does not represent a heavy computational and signaling burden, while retaining most of the improvements brought by the spectrum sharing paradigm.
Performance Analysis of AODV-UI Routing Protocol With Energy Consumption Improvement Under Mobility Models in Hybrid Ad hoc Network

Abstract —In mobile ad hoc networks (MANETs), routing protocol plays the most important role. In the last decade, Ad hoc On-demand Distance Vector (AODV) routing protocol becomes the attention of focussed research on MANETs world wide. A lot of protocols had been proposed to improve and optimize AODV routing protocol to achieve the best in quest of reliable protocol. In this paper, we present some improvement suggestion to AODV routing protocol. Our proposed protocol, called AODV-UI, improved AODV in gateway interconnection, reverse route and in energy consumption. We also measure performance indicators for some metrics, such as energy, routing overhead, end-to-end delay, and packet delivery ratio. We performed our simulation scenarios with three mobility model with different maximum speed and sources in hybrid ad hoc network. The result shows that AODV-UI is more stable when it is used in random way point mobility model in any speed and number of sources.

One cannot ʺjust askʺ about experience

The present article concentrates on second-person indepth phenomenological inquiry (SIPI) into human experience. In order to delineate important characteristics of SIPI we use an example of a phenomenological case study. The study comprised of descriptive experience sampling, writing of diary, and a series of elicitation interviews.
Identifying Rootkit Infections Using Data Mining

Rootkits refer to software that is used to hide the presence and activity of malware and permit an attacker to take control of a computer system. In our previous work, we focused strictly on identifying rootkits that use inline function hooking techniques to remain hidden. In this paper, we extend our previous work by including rootkits that use other types of hooking techniques, such as those that hook the IATs (Import Address Tables) and SSDTs (System Service Descriptor Tables). Unlike other malware identification techniques, our approach involved conducting dynamic analyses of various rootkits and then determining the family of each rootkit based on the hooks that had been created on the system. We demonstrated the effectiveness of this approach by first using the CLOPE (Clustering with sLOPE) algorithm to cluster a sample of rootkits into several families; next, the ID3 (Iterative Dichotomiser 3) algorithm was utilized to generate a decision tree for identifying the rootkit that had infected a machine.
Health Signal Generation in the ORCA (Organic Robot Control Architecture) Framework

This paper evaluates various information-theoretical methods for the generation of health signals in the Organic Robot Control Architecture (ORCA). Also a new method based on the joint probability distribution of signals is proposed. The results show that the new method is superior to the known ones for the studied worst-case artificial and real scenarios. As an example for the application of health signals in ORCA, an adaptable path planner is described which considers the health status of a partially damaged robot.
Assays Uptake and binding of ~ 51-zymosan

Circulating monocytes and tissue macrophages (Me) 1 secrete complement proteins and have distinct receptors for some of these secreted products. Although hepatocytes and possibly epithelial cells are major sources of plasma complement (1), Mcl synthesize C1 subcomponents (2, 3), C4 (4, 5), C2 (5-7) C5 (8), C3 (2, 8) and all the components of the alternative pathway and its control proteins (8). Current evidence indicates that M~ bear at least two distinct receptors for fragments of activated C3 (9, 10). The type one complement receptor, CR1 (205 kD) displays specificity for activated C3 (C3b) (11) and C4 (C4b) (12). CR 1 interacts with iC3b, the product of C3b cleavage by factor I (9), although anti-CR 1 antibodies that block C3b-dependent rosetting do not block iC3b-dependent rosetting (13, 14). The type three complement receptor, CR3, (170 and 95 kD) interacts with iC3b, and possibly with the further degradation product C3dg (9). In order to investigate the physiological role of M¢ complement products we made use of monoclonal antibodies (ab) that are specific for CR1 (13) and that recognize epitopes associated with CR3 (15, 16). We found that deposition of M~-derived C3 on the acceptor surface of zymosan particles mediated binding and ingestion of zymosan via M~ CR3. Zymosan uptake could also be mediated via mannosyl, fucosyl receptors (MFR, 17) in those M~ populations that possess both CR3 and MFR activity (18). These studies indicate a role for M~ complement in local opsonization and host defense.
Discovering Abnormal Patches and Transformations of Diabetics Retinopathy in Big Fundus Collections

Diabetic retinopathy (DR) is one of the retinal diseases due to long-term effect of diabetes. Early detection for diabetic retinopathy is crucial since timely treatment can prevent progressive loss of vision. The most common diagnosis technique of diabetic retinopathy is to screen abnormalities through retinal fundus images by clinicians. However, limited number of well-trained clinicians increase the possibilities of misdiagnosing. In this work, we propose a big-data-driven automatic computer-aided diagnosing (CAD) system for diabetic retinopathy severity regression based on transfer learning, which starts from a deep convolutional neural network pre-trained on generic images, and adapts it to large-scale DR datasets. From images in the training set, we also automatically segment the abnormal patches with an occlusion test, and model the transformations and deterioration process of DR. Our results can be widely used for fast diagnosis of DR, medical education and public-level healthcare propagation.
A decision-analytic approach for P2P cooperation policy setting

While overall performance of peer-to-peer systems depends strongly on the amount of resource contributions made by individual peers, autonomous and rational peers make decisions on their cooperation policies (resource contributions) according to their individual utilities. To deal with the inherent conflict among individual utilities of the rational peers to improve overall performance of the system, we propose a decision-analytic approach that determines the appropriate cooperation policies of the individual peers in a distributed manner and coordinates their rational decisions in compliance with the social welfare improvement.
Who Dat Say (We) "Too Depraved to Be Saved"?: Re-membering Katrina/ Haiti (and Beyond): Critical Studyin'for Human Freedom

In this essay, Joyce King attempts to interrupt the calculus of human (un)worthiness and to repair the collective cultural amnesia that are legacies of slavery and that make it easy—hegemonically and dysconsciously—for the public to accept myths and media reports, such as those about the depravity of survivors of Hurricane Katrina in New Orleans and the earthquake in Haiti. King uses examples of Black Studies scholarship within a critical studyin' framework to recover and re-member the historical roots of resistance and revolution and the African cultural heritage that New Orleans and Haiti have in common. Within this framework, teachers, students, and parents can combat ideologically biased knowledge, disparaging discourses of Blackness, and dehumanizing disaster narratives.
Computation of static and dynamic axial and radial forces on power transformer windings due to inrush and short circuit currents

In this paper, the radial and axial forces due to inrush and short circuit currents on both inner and outer surfaces of low voltage (LV) and high voltage (HV) windings are calculated. Static and dynamic aspects of these forces which are related to the variation of forces versus winding height and time are analyzed. Power transformer in the start-up mode and under short circuit fault is modeled using two-dimensional (2D) time stepping finite element method (TSFEM). This approach leads to the precise determination of the required signals including current, magnetic flux density, radial and axial forces. Calculated forces are analyzed significantly to compare impacts of the mechanical forces due to inrush and short circuit currents on the windings of the transformer. Three-dimensional (3D) TSFEM is utilized to evaluate aforementioned forces and compare with 2D TSFEM results. In the 3D TSFEM, geometrical and physical characteristics of the all components of the transformer, nonlinearity of the core materials and distribution of the primary and secondary windings are taken into account. 2D TSFEM results are verified by 3D TSFEM results.
Chunk : A Framework for Modular Distributed Shared Memory Systems

We present Chunk, a framework for building modular distributed shared memory systems for UNIX. Chunk allows applications that are designed to share local memory through the UNIX memory mapped file mechanism (mmap) to be able to share memory across different physical hosts without modifications. Chunk’s modular architecture enables the use of a variety of memory-sharing policies. We present a DSM system implemented using the Chunk framework and evaluate its performance. We demonstrate the viability of our framework for real-world applications by presenting experiments with Berkeley DB.
Effect of systolic blood pressure reduction on hematoma expansion, perihematomal edema, and 3-month outcome among patients with intracerebral hemorrhage: results from the antihypertensive treatment of acute cerebral hemorrhage study.

BACKGROUND Evidence indicates that systolic blood pressure (SBP) reduction may reduce hematoma expansion in patients with intracerebral hemorrhage (ICH) who are initially seen with acute hypertensive response. OBJECTIVE To explore the relationship between different variables of SBP reduction and hematoma expansion, perihematomal edema, and 3-month outcome among patients with ICH. DESIGN Post hoc analysis of a traditional phase 1 dose-escalation multicenter prospective study. SETTING Emergency departments and intensive care units. PATIENTS Patients having ICH with an elevated SBP of at least 170 mm Hg who were seen within 6 hours of symptom onset. INTERVENTION Systolic blood pressure reduction using intravenous nicardipine hydrochloride targeting 3 tiers of sequentially escalating SBP reduction goals (170-199, 140-169, or 110-139 mm Hg). MAIN OUTCOME MEASURES We evaluated the effect of SBP reduction (relative to initial SBP) on the following: hematoma expansion (defined as an increased intraparenchymal hemorrhage volume >33% on 24-hour vs baseline computed tomographic [CT] images), higher perihematomal edema ratio (defined as a >40% increased ratio of edema volume to hematoma volume on 24-hour vs baseline CT images), and poor 3-month outcome (defined as a modified Rankin scale score of 4-6). RESULTS Sixty patients (mean [SD] age, 62.0 [15.1] years; 34 men) were recruited (18, 20, and 22 patients in each of the 3 SBP reduction goal tiers). The median area under the curve (AUC) (calculated as the area between the hourly SBP measurements over 24 hours and the baseline SBP) was 1360 (minimum, 3643; maximum, 45) U. Comparing patients having less vs more aggressive SBP reduction based on 24-hour AUC analysis, frequencies were 32% vs 17% for hematoma expansion, 61% vs 40% for higher perihematomal edema ratio, and 46% vs 38% for poor 3-month outcome (P > .05 for all). The median SBP reductions were 54 mm Hg at 6 hours and 62 mm Hg at 6 hours from treatment initiation. Comparing patients having equal to or less vs more than the median SBP reduction at 2 hours, frequencies were 21% vs 31% for hematoma expansion, 42% vs 57% for higher perihematomal edema ratio, and 35% vs 48% for poor 3-month outcome (P > .05 for all). CONCLUSIONS We found no significant relationship between SBP reduction and any of the outcomes measured herein; however, the Antihypertensive Treatment of Acute Cerebral Hemorrhage study was primarily a safety study and was not powered for such end points. The consistent favorable direction of these associations supports further studies with an adequately powered randomized controlled design to evaluate the efficacy of aggressive pharmacologic SBP reduction.
Sexual communication, dyadic adjustment, and psychosexual well-being in premenopausal women with self-reported dyspareunia and their partners: a controlled study.

INTRODUCTION Although research that takes into account partner and relationship factors in dyspareunia is slowly emerging, little is known about how these couples communicate about their sexuality. Additionally, partner psychosexual adjustment has not been examined in a controlled fashion. AIM This study aimed to compare dyadic sexual communication, dyadic adjustment, psychological adjustment, and sexual well-being of women with self-reported dyspareunia and their partners with those of pain-free control women and their partners. METHODS Premenopausal women (n = 38; mean [M] age = 24.92) with self-reported dyspareunia, their partners (n = 38; M age = 26.71), as well as pain-free control women (n = 44; M age = 25.86) and their partners (n = 44; M age = 27.95) completed an online survey measuring dyadic sexual communication, dyadic adjustment, anxiety, depression, sexual functioning, and sexual distress. MAIN OUTCOME MEASURES Assessments of women and men's (i) dyadic sexual communication; (ii) dyadic adjustment; (iii) anxiety; (iv) depression; (v) sexual functioning; and (vi) women's sexual distress were the main outcome measures. RESULTS Compared with pain-free controls, women with dyspareunia reported significantly poorer dyadic sexual communication, a difference not found between partners of women with dyspareunia and control partners. Compared with partners of control women, those of women with dyspareunia reported significantly more impaired sexual functioning. No differences in dyadic adjustment were found between women with dyspareunia and pain-free control women, or between their respective partners. Finally, compared with control women, those with dyspareunia reported significantly more impaired psychological and sexual well-being. CONCLUSIONS Findings suggest that dyspareunia impacts not only the psychosexual adjustment of affected women but also that of their partners. It seems relevant to include both members of the couple in future research and treatment for dyspareunia.
Cardiovascular variability signals: towards the identification of a closed-loop model of the neural control mechanisms

The authors consider parametric methods for processing cardiovascular signals and try to provide a global, although indirect evaluation of some neural regulatory activities. In particular, the variability signals of the heart rate (under the form of interval tachogram) and arterial blood pressure (systogram) together with respiratory movement signal (respirogram) are considered as inputs to a closed-loop model which describes a few aspects of the physiological interactions among the signals themselves. The identifiability of the transfer function of the model is demonstrated from the joint process black-box description of the signals. A direct identification procedure is proposed dividing the system into two dynamic adjustment models. A few suggestions are deduced on how and where the respirogram enters the model and on the genesis of the 10-s rhythm, parameters relevant to the Starling effect, Windkessel model, and the gain of baroreceptor mechanisms. The approach presented is intended also to provide a general frame for closed-loop identification in different pathophysiological conditions. <<ETX>>
The Catalog of Human Hair Keratins

The human type I hair keratin subfamily comprises nine individual members, which can be subdivided into three groups. Group A (hHa1, hHa3-I, hHa3-II, hHa4) and B (hHa7, hHa8) each contains structurally related hair keratins, whereas group C members hHa2, hHa5, and hHa6 represent structurally rather unrelated hair keratins. Antibodies produced against these individual hair keratins, first analyzed for specificity by one- dimensional Western blots of total hair keratins, were used to establish the two-dimensional catalog of the human type I hair keratin subfamily. The catalog comprises two different series of type I hair keratins: a strongly expressed, Coomassie-stainable series containing hair keratins hHa1, hHa3-I/II, hHa4, and hHa5, and a weakly expressed, immunodetectable series harboring hHa2, hHa6 hHa7, and hHa8. In situ hybridization and immunohistochemical expression studies on scalp follicles show that two hair keratins, hHa2 and hHa5, define the early stage of hair differentiation, i.e. hHa5 expression in hair matrix and hHa5/hHa2 coexpression in the early hair cuticle cells. Whereas cuticular differentiation proceeds without the expression of further type I hair keratins, matrix cells embark on the cortical pathway by sequentially expressing hHa1, hHa3-I/II, and hHa4, which are supplemented by hHa6 at an advanced stage of cortical differentiation, and hHa8, which is expressed heterogeneously in cortex cells. Thus, six type I hair keratins are involved in the terminal differentiation of anagen hairs. The expression of hHa7 is conspicuously different from that of the other hair keratins in that it does not occur in the large anagen follicles of terminal scalp hairs but only in central cortex cells of the rare and small follicle type that gives rise to vellus hairs.
As configurações comunicativas de mundos midiatizados: pesquisa da midiatização na era da “mediação de tudo”

When various media in their entirety mark how we articulate our social worlds, we need an approach of mediatization research that reflects this transmediality. To develop such an approach, the article discusses the institutionalist and social-constructivist traditions of mediatization research. Both concur that mediatization is a concept to capture the interrelation between the change of media and communication, and the change of culture and society. Such a conceptual reflection offers the chance to view the mediatization as the change of transmedial communicative figurations. Based on this theoretical foundation, the article reflects a twofold operationalization, i.e. as diachronous and synchronous mediatization research.
