Comprehensive Characterization of an Open Source Document Search Engine

This work performs a thorough characterization and analysis of the open source Lucene search library. The article describes in detail the architecture, functionality, and micro-architectural behavior of the search engine, and investigates prominent online document search research issues. In particular, we study how intra-server index partitioning affects the response time and throughput, explore the potential use of low power servers for document search, and examine the sources of performance degradation ands the causes of tail latencies. Some of our main conclusions are the following: (a) intra-server index partitioning can reduce tail latencies but with diminishing benefits as incoming query traffic increases, (b) low power servers given enough partitioning can provide same average and tail response times as conventional high performance servers, (c) index search is a CPU-intensive cache-friendly application, and (d) C-states are the main culprits for performance degradation in document search.
How to combat long echoes in OFDM transmission schemes: sub-channel equalization or more powerful channel coding

The OFDM technique with guard-time, which has been proposed for terrestrial digital image and digital audio broadcasting applications in Europe, is an interesting approach to combat the frequency selectivity of the channel. However, it is sensitive to the interference caused by echoes longer than the guard-time. The aim of this article is twofold. First, the effects of the guard interval on a real case multipath channel are analyzed for an OFDM transmission system. The system performance is analytically derived as a function of the guard interval. The sensitivity of the OFDM system to the interference caused by echoes exceeding the guard-time is analyzed. The degradation due to the interference can be restored by applying two different techniques: using more powerful channel coding or employing sub-channel equalization. For channel coding, a combination of multilevel coding with multiresolution modulation, which is proposed for a digital terrestrial TV broadcasting, is used. The sub-channel equalizer is based on the DFE, where its adaptation calls-upon the LMS-algorithm, using the reference symbols sent periodically. Simulation results show that using powerful channel coding, rather than equalization, can partly restore the degradation caused by a shorter guard-time.
Catheter associated urinary tract infection in an acute care setting of a tertiary care centre in South India

Background: Catheter associated UTI is a serious cause of morbidity and mortality in intensive care unit (ICU) patients. Hence, authors undertook the present study to know the prevalence of catheter associated urinary tract infections (CAUTI) in medical ICU patients of tertiary care centre and to know the antibiotic resistance pattern of the causative organisms.Methods: A one-year prospective study was carried out from September 2015 to August 2016. Demographic data from the catheterized patients were collected daily and scrutinized for the signs and symptoms as per CDC criteria for confirmation as CAUTI. Relevant antimicrobial resistance data of etiologic agents were also collected to ascertain the prevalent resistance pattern.Results: The overall incidence of CAUTI was 14.69 per 1000 catheterized days in the present study. Out of the 37 diagnosed CAUTI cases, 12 (32.4%) were males and 25 (67.6%) were females with maximum patients being between 40 to 60 years of age. The commonest uropathogens was Escherichia coli (n=26) followed by K. pneumoniae (n=5). Both Escherichia coli and Klebsiella pneumoniae isolates were found to be 100% resistant to cefotaxime, ceftazidime and cefuroxime. Pseudomonas aeruginosa and Acinetobacter species were least common etiological culprits and demonstrated complete resistance to all the tested antibiotics.Conclusions: In the present study the prevalence of CAUTI is much higher which needs to be rectified by continuous monitoring and training of the staff in implementation of infection control practices in a proactive manner.
Can the Modified-Conventional Teaching Method be Effective for Motivating Students’ Foreign Language Context?

Students were often confused and forced into silence when they communicate in English. This condition became a problem during the teaching-learning process and may eventually lead to poor speaking ability. Modified-Conventional method, which imbedded to the student center learning (SCL) in a collaborative learning can be a solution to address the aforementioned condition. The reason for the hypothesis above is the presence of the underlying principles of such the innovative teaching that can foster students’ motivation, both intrinsically and extrinsically, towards the foreign language learning. The objective of this study is finding out the effectiveness of implementing the modified-conventional method in a collaborative learning, to the students’ learning motivation of EFL context which could boost their oral communication. Participants were 30 fourth semester students (16 males and 14 females) enrolled in a three-year diploma program in Travel and Tourism Business, State Polytechnic of Bali. The students were given communicative activities and practices which were carefully designed so as to necessitate the implementation of the modifiedconventional method. Data were collected through classroom action-based research procedures starting from planning, action, observation, and reflection. The mean was used measure of the students’ speaking achievement in order to identify any statistically significant improvements following the intervention. Meanwhile, qualitative data was analyzed based on the whole observation of the action and the result of the questionnaires. The result of the pre-test indicated that the students’ oral communication categorized into low. Its mean score was only 55.29. Meanwhile, the results of test in the three cycles were respectively 68.30, 75.12, and 86.22. It can be concluded that the students’ learning motivation increased highly due to the conducive learning atmosphere created as they could get engage, encourage, enthusiastic, and explored in each learning cycle. Consequently, it could improve their oral communication significantly. Limitations and suggestions for successful applied action-integrated instruction and implications for future research
Emergency logistics for disaster management under spatio-temporal demand correlation: The earthquakes case

Emergency logistics is crucial to ameliorate the impact of large earthquakes on society. We present a modeling framework to assist decision makers in strategic and tactical planning for effective relief operations after an earthquake's occurrence. The objective is to perform these operations quickly while keeping its total expenses under a budget. The modeling framework locates/allocates resources in potentially affected zones, and transportation capacity is dynamically deployed in those zones. Demand uncertainty is directly incorporated through an impulse stochastic process. The novelty of this approach is threefold. It incorporates temporo-spatial dependence and demands heterogeneity. It incorporates the availability of transportation capacity at different zones. It incorporates tight budget constraints that precludes the total satisfaction of demands. The resulting model is a large size stochastic mixed-integer programming model, which can be approximately solved through Sample Average Approximation. An example is provided and a thorough sensitivity analysis is performed. The numerical results suggest that that the response times are highly sensitive to the availability of inventory at each period. In addition, all logistics parameters (except for inventory capacity) have approximately the same impact on the total response time. The elasticity for all these parameters indicate constant returns to scale.
The Role of Serial Dependence in Visual Perception

Author(s): Liberman, Alina | Advisor(s): Whitney, David | Abstract: From moment to moment, we perceive objects in the world as continuous despite fluctuations in their image properties due to factors like occlusion, visual noise, and eye movements. The mechanism by which the visual system accomplishes this object continuity remains elusive. Recent results demonstrate that the perception of low-level stimulus features such as orientation and numerosity is systematically biased (i.e. pulled) towards visual input from the recent past. The spatial region over which current orientations are pulled by previous orientations is known as the continuity field, which is temporally tuned for the past 10-15 seconds. This perceptual pull could contribute to the visual stability of low-level features over short time periods, but it does not address how visual stability occurs at the level of complex objects or during visual discontinuities. Here, we examined whether the visual system facilitates stable perception by biasing current perception of objects towards recently seen objects, and whether it operates across disruptions in visibility. First, we used psychophysics to show that the perception of face identity is systematically biased towards identities seen up to several seconds prior, even across changes in viewpoint. This perceptual bias did not depend on subjects’ prior responses or on the method used to measure identity perception. Next, we tested whether this serial dependence, or positive perceptual pull, helps stabilize perceived expression. To test this, observers judged random facial expressions (ranging from happy to sad to angry). We found a pull in perceived expression toward previously seen expressions, but only when the 1-back and current face shared the same identity. Finally, we examined whether the continuity field helps maintain perceived object identity during occlusion. Specifically, we found that the perception of an oriented Gabor that emerged from behind an occluder was significantly pulled towards the random (and unrelated) orientation of the Gabor that was seen entering the occluder. Importantly, this serial dependence was stronger for predictable, continuously moving trajectories, compared to unpredictable ones or static displacements. While this serial dependence in object perception manifests as a misperception, it is adaptive: visual processing echoes the stability of objects in the world to create perceptual continuity. These results provide further evidence for the existence of an object-selective continuity field that helps maintain perceived object stability over time and across visual noise or disruptions.
Trauma management in a tertiary care hospital in Peshawar, Pakistan.

BACKGROUND With an increasing incidence of road traffic accidents and weapon injuries there is increasing need for improvement in trauma management. Liver being a highly vascular organ and strategically located is difficult to manage. METHODS Study was conducted in Surgical 'A' Unit, Lady Reading Hospital, Peshawar from August 2003 to September 2005. It was a descriptive study and all patients were operated in emergency department. All relevant data of patients were recorded from the emergency and admission protocols. RESULTS A total of 364 trauma patients were received and among those 48 patients had liver trauma, 75% of patients had penetrating and 25% had blunt trauma. Most of the patients had grade III liver injuries. There were no grade V and VI injury. Repair with perihepatic packing for liver injuries remains the most frequently performed procedure (41% of patients). CONCLUSION In a stable patient blunt trauma liver can be managed conservatively by serial examinations and investigations with emergency laparotomy facilities at hand. Perihepatic packing and damage control surgery is the valuable procedure at hand. Increasing grades of liver injuries leads to increasing morbidity and mortality. The same is the case with multiple organ injuries.

Task-based teaching of micro-skills in an EAP situation

The present study investigated the reading comprehension of English language learners in EAP (English for Academic Purposes) situations via a task-based language teaching (TBLT) approach. Forty-two students on an MBA course were selected as participants, and randomly divided into two groups. The participants in the experimental group were taught four reading skills namely, scanning, skimming, contextual clues, and critical reading through task-based language teaching, but the control group received the same hours of instruction through translation. Having received the instruction, participants took a final examination, which was designed to test reading micro-skills. Then a comparison was made by an independent-samples t-test to find possible differences between the two groups. The results revealed that students who were taught reading skills via TBLT had a better academic performance, and reading comprehension was more effective.
Association of Body Mass Index with Dyslipidemia among the Government Staff of Kermanshah, Iran: A Cross-Sectional Study

Background: There is some evidence suggesting that Body Mass Index (BMI) may increase plasma lipoprotein levels. Objectives: This study aimed to evaluate the possible association between BMI and dyslipidemia among the government staff of Kermanshah. Methods: This descriptive-analytical cross-sectional study was performed on the staff of 13 governmental organizations in Kermanshah (a city located in the west of Iran) in 2012. The staff was recruited using census method. We obtained information of 1496 staff aged 22 - 69 through the standardized stepwise questionnaire for NCDs risk factor surveillance. The staff was then physically examined by trained persons. Finally, their blood samples were obtained. Results: The prevalence of dyslipidemia was 16.6% in the study group, with the prevalence of 18.2% in men and 7.9% in women. There were also 53% (55.8% in men and 7.9% in women) and 17.8% (17.6% in men and 38.1% in women) prevalence rates for overweight and obesity, respectively. Dyslipidemia was significantly associated with factors such as BMI (P value = 0.004), gender (P value < 0.001), marital status (P value = 0.01), cigarette smoking (P value = 0.008), and hookah smoking (P value = 0.002), but not with passive smoking, age, education level, physical activity, FBS (fast blood sugar), WHR (waist to hip ratio), hypertension, waist size, and hip size. In the adjusted model, there was a link merely between obesity and dyslipidemia while no statistically significant association was found between dyslipidemia and overweight. Moreover, a non-linear dose-response association was observed between dyslipidemia and BMI. Conclusions: Since dyslipidemia was significantly prevalent among men, fat people, and smokers, a particular attention is crucial to be paid to these groups.
Millimeter-Wave-Based Cooperative Backhaul for a Mobile Station in an X-Haul Network

In this paper, we propose a millimeter-wave-based cooperative backhaul scheme for a mobile X-haul distributed unit (XDU), whose line of sight for backhaul data reception is not always guaranteed in an X-haul network. Since the received signal at the mobile XDU experiences severe path loss than other stationary XDUs, the proposed scheme selects one of stationary wireless XDUs as a relay for assisting the mobile XDU. The relaying XDU selection takes into account not only the location information, but also the load information of wireless XDUs. We derive the outage probability of the mobile XDU and show that the proposed scheme outperforms the conventional relay selection scheme without taking account of the traffic load on relaying nodes.
AWARENESS OF FARMERS REGARDING HYGIENIC HANDLING OF THEIR CATTLE TO PREVENT ZOONOTIC DISEASES

Villagers have got the habit to remain in close contact with their cattle which may lead to spread of zoonotic diseases. Once concept of hygienic animal handling is assessed, effective measures can be taken to prevent the zoonotic transmission of diseases. With this aim, 270 farmers from nine villages of nine Gram Panchayet of Murarai-II block of Birbhum district, West Bengal, India were selected randomly. They were personally interviewed with twelve questions related with such knowledge. A score of 1 was given for correct answer and 0 for other answer including wrong and unknown answer. After analysis of data, a mean score of 7.96 was obtained by the farmers. Only significantly higher result was scored by the age group of 20-30 years farmers but in the rest age groups there were no significant differences. Positive correlation was observed between the knowledge score and education level. Better knowledge score was noted among the farmers having more number of animals. Male respondents and respondents having training related to animal husbandry scored better (P < _ 0.05). In the present study most of the farmers found to have minimum knowledge about the hygienic handling of their cattle.
A Survey on Autonomic Provisioning and Management of QoS in SDN Networks

In today’s Internet, killer network services and applications, such as video and audio streaming, network storage, and online video games, are pushing the network infrastructure resources to the edge. By design and for the most part, the Internet is the best offer delivery ecosystem with little or no end-to-end quality-of-service (QoS) guarantees. Even, frameworks, such as IntServ and DiffServ that were designed and implemented to provide QoS guarantees, still fail to solve this problem at a wide scale. Software-defined networking (SDN) is a fast emerging networking paradigm that promises to provide end-to-end QoS guaranteeing by offering greater network flexibility, abstraction, control, and programmability to network resources. In this paper, we review, survey, and discuss the current state of the art on QoS provisioning in the area of SDN, with respect to applying the concept of autonomic computing (AC) to automatically support, provision, monitor, and maintain QoS requirements. This paper includes in-depth classification, taxonomy, and comparative analysis for the autonomic-based QoS provisioning in accordance with the famous influential and widely adopted the monitor-analyze-plan-execute-knowledge (MAPE-K) IBM architectural model for autonomic computing.
Enfermedad crónica y sufrimiento: revisión de literatura

A literature review was conducted for an insight into the progress nursing has made with respect to the care of chronically ill patients, their families and their suffering, as well as the instruments proposed to measure it. The review was based on several descriptors; namely, suffering, instruments, chronically ill, nursing (limited to the chronically ill person who is suffering), and the scale used to evaluate it. The SciELO, NursingConsult, Redalyc, Dialnet, and EBSCOhost databases were searched, and a total of 116 articles were reviewed. Out of that group, 40 articles dealing with chronicity and its emotional impact on persons, suffering, nursing care and the instruments used
Restaurant Point-of-Sale Interfaces: Comparisons in Menu Organization and User Efficiency

Careful considerations in designing and organizing information for restaurant point-of-sale (POS) systems can affect user experience. Unfortunately, usability guidelines are sparse for these systems. Applications from other studies, such as categorical organization and F-shape, are implemented in an experimental interface as a starting point of discussion. A control interface was designed after the default version of NCR Aloha’s POS program: Aloha Table Service. Novice and expert order taking strategies were also observed to compare input differences. This study examined selection time, total time, and selection accuracy across both order and interface types. The results show that time and number of key presses are significantly reduced under the treatment interface, and that teaching expert order taking strategies to novice users may help reduce cognitive load.
Optimal best-case and worst-case coverage for straight paths in ad hoc networks

Abstract Given a set of network nodes and their locations, the best support path problem is to find a path that has the min-max distance to network nodes and the maximal breach path problem is to find a path that has the max-min distance to network nodes. This paper considers straight paths and proposes optimal algorithms identifying both the best support and the maximal breach straight paths. Our study provides a coverage measurement method for straight paths in an ad hoc network. Based on computational geometry and graph theory, we propose plane-sweep algorithms to find the optimal straight paths for both the best-case and worst-case coverage problems in polynomial time. Mathematical analysis and simulations are used to prove the optimality of proposed algorithms.

MADneSs: A Multi-Layer Anomaly Detection Framework for Complex Dynamic Systems

Anomaly detection can infer the presence of errors without observing the target services, but detecting variations in the observable parts of the system on which the services reside. This is a promising technique in complex software-intensive systems, because either instrumenting the services’ internals is exceedingly time-consuming, or encapsulation makes them not accessible. Unfortunately, in such systems anomaly detection is often ineffective due to their dynamicity, which implies changes in the services or their expected workload. Here we present our approach to enhance the efficacy of anomaly detection in complex, dynamic software-intensive systems. After discussing the related challenges, we present MADneSs, an anomaly detection framework tailored for the above systems that includes an adaptive multi-layer monitoring module. Monitored data are then processed by the anomaly detector, which adapts its parameters depending on the current system behavior. An anomaly alert is provided if the analysis conducted by the anomaly detector identify unexpected trends in the data. MADneSs is evaluated through an experimental campaign on two service-oriented architectures; software faults are injected in the application layer, and detected through monitoring of underlying system layers. Lastly, we quantitatively and qualitatively discuss our results with respect to state-of-the-art solutions, highlighting the key contributions of MADneSs.
