In vitro biofilm formation and antimicrobial susceptibility patterns of bacteria isolated from suspected external ocular infected patients attending Jimma University Medical Center eye clinic, southwest Ethiopia

Background: Ocular disease with its complications is a major public health problem which significantly impacts on quality of life in developing countries. An ocular infection due to microbial agents, can lead to reduced vision and blindness. This study was aimed to assess the antimicrobial susceptibility pattern and biofilm forming potential of bacteria isolated from suspected external ocular infected patients attending Jimma University Medical Center (JUMC). Method: A cross sectional facility based study was conducted on 319 suspect patients with external ocular infections from March 2017 to June 2017 at JUMC in Southwest Ethiopia. External ocular specimens were collected and standard operating procedures were followed to handle and culture throughout the study period. Antimicrobial susceptibility pattern of the isolates was determined by disk diffusion method according to CLSI 2015. Microtiter (96 wells) plate method was used to screen biofilm formation by measuring optical density at 570nm. Result: Out of 319 study participants with external ocular infection, the prevalence of bacterial pathogens was 46.1%. The predominant bacterial isolates were Coagulase negative staphylococcus (CoNS) (27.7%) followed by Staphylococcus aureus (19.7%). Among Gram negatives, Pseudomonas aeroginosa (6.8%) was the leading isolate. Increased antimicrobial resistance was observed for tetracycline (64%), erthromycin (66.7%) and penicillin (77.1%). Amoxicillin-clavulanic acid, ciprofloxacin and gentamicin were the most effective drugs for both Gram negative and Gram positive ranging from about 70 to 100% with the later two drugs for external ocular infections. Methicillin resistant S. aureus (MRSA) accounted for 13.8% of S. aureus isolates. Multidrug resistance (MDR) accounted for 68.7%. The overall biofilm formation rate of bacterial ocular pathogens was 66.1%; with P. aeruginosa (40%), CoNS (34.1%) and S. aureus (31%) formed strong biofilm phenotype. Conclusion: The prevalence of bacterial isolates among external ocular infection was high. Almost all bacterial isolates were resistant to atleast one or more drugs. MDR pathogens were observed increasingly among biofilm formers or vice versa. Therefore, antimicrobial susceptibility testing should be practiced to guide treatment of external ocular cases and to control the emergence of drug resistant bacteria.
A system of human vital signs monitoring and activity recognition based on body sensor network

Purpose – The purpose of this paper is to develop a health monitoring system that can measure human vital signs and recognize human activity based on body sensor network (BSN). Design/methodology/approach – The system is mainly composed of electrocardiogram (ECG) signal collection node, blood oxygen signal collection node, inertial sensor node, receiving node and upper computer software. The three collection nodes collect ECG signals, blood oxygen signals and motion signals. And then collected signals are transmitted wirelessly to receiving node and analyzed by software in upper computer in real-time. Findings – Experiment results show that the system can simultaneously monitor human ECG, heart rate, pulse rate, SpO2 and recognize human activity. A classifier based on coupled hidden Markov model (CHMM) is adopted to recognize human activity. The average recognition accuracy of CHMM classifier is 94.8 percent, which is higher than some existent methods, such as supported vector machine (SVM), C4.5 decision.
Benchmarking of Control Strategies for Wastewater Treatment Plants

Wastewater treatment plants are large non-linear systems subject to large perturbations in wastewater flow rate, load and composition. Nevertheless these plants have to be operated continuously, meeting stricter and stricter regulations. Many control strategies have been proposed in the literature for improved and more efficient operation of wastewater treatment plants. Unfortunately, their evaluation and comparison – either practical or based on simulation – is difficult. This is partly due to the variability of the influent, to the complexity of the biological and biochemical phenomena and to the large range of time constants (from a few minutes to several days). The lack of standard evaluation criteria is also a tremendous disadvantage. To really enhance the acceptance of innovative control strategies, such an evaluation needs to be based on a rigorous methodology including a simulation model, plant layout, controllers, sensors, performance criteria and test procedures, i.e. a complete benchmarking protocol. This book is a Scientific and Technical Report produced by the IWA Task Group on Benchmarking of Control Strategies for Wastewater Treatment Plants . The goal of the Task Group includes developing models and simulation tools that encompass the most typical unit processes within a wastewater treatment system (primary treatment, activated sludge, sludge treatment, etc.), as well as tools that will enable the evaluation of long-term control strategies and monitoring tasks (i.e. automatic detection of sensor and process faults). Work on these extensions has been carried out by the Task Group during the past five years, and the main results are summarized in Benchmarking of Control Strategies for Wastewater Treatment Plants . Besides a description of the final version of the already well-known Benchmark Simulation Model no. 1 (BSM1), the book includes the Benchmark Simulation Model no. 1 Long-Term (BSM1_LT) – with focus on benchmarking of process monitoring tasks – and the plant-wide Benchmark Simulation Model no. 2 (BSM2).

Organisational Performance and Manufacturing Practices

Total quality management, just-in-time, total preventive management and supply-chain partnership are all seen as modern manufacturing practices. They are often subsumed under umbrella concepts, such as Womack, Jones & Roos’s (1990) lean production, Dean & Snell’s (1991) integrated manufacturing, and Schonberger’s (1986) world class manufacturing. Total quality management (TQM) may itself be one such umbrella concept (Cooney & Sohal, this book). Within social theory they have been viewed as a vital part of the postFordist model, “Toyotaism” in some people’s terms (Wood, 1989). The contrast is often drawn between this new approach to management and the excessively rigid Fordist system, which was based on Taylorist principles of job design, with a narrow division of labour, highly functional management and low role demands for the mass of workers. Womack et al. (1990) encouraged the differentiation of lean production from mass production, while TQM has been portrayed by some as a major cultural force—an enterprise lifestyle (McCloskey & Collett, 1993)—which represents a radical change in the way organisations operate. Portrayed in such terms, lean production and TQM became in the late 1980s panaceas for management and the ills of Western economies: the low productivity, poor quality and industrial conflict. Their extension to all fields of industry and commerce was urged. Womack et al. (1990, p. 277), indeed, proclaimed that lean production would become “the standard global production system of the twenty-first century”, seemingly taking it for granted that their exhortations would be heeded. Having conceived the management methods of lean production literally as a machine, they effectively turned it into a juggernaut that would eliminate in one fell swoop many, if not all, of the production, organisational and personnel problems associated with post-war Western economies. Prescriptive packages of practices tend to be all-embracing concepts that offer a fresh way of thinking, as well as urgently needed practices. In the case of lean production, the emphasis is on viewing the organisation in the context of its suppliers and customers and in terms of a flow of activities pulled by the customer. The aim is to eliminate all elements of this system that add no value to the customer. Lean production and other such approaches were part of a movement to elevate operational management within the overall concerns of management (Abernathy, Clark & Kantrow, 1984). Prior to this, the over-riding emphasis of
Janus: an Approach for Confinement of Untrusted Applications

Security is a serious concern on today''s computer networks. Many applications are not very good at resisting attack, and our operating systems are not very good at preventing the spread of any intrusions that may result. In this thesis, we propose to manage the risk of a security breach by confining these untrusted (and untrustworthy) applications in a carefully sanitized space. We design a secure environment for confinement of untrusted applications by restricting the program''s access to the operating system. In our prototype implementation, we intercept and filter dangerous system calls via the Solaris process tracing facility. This enables us to build a simple, clean, user-mode mechanism for confining untrusted applications. Our implementation has negligible performance impact, and can protect pre-existing legacy code.
Fabrication and performance of tuneable single-mode VCSELs emitting in the 750- to 1000-nm range

The growing demand on low cost high spectral purity laser sources at specific wavelengths for applications like tuneable diode laser absorption spectroscopy (TDLAS) and optical pumping of atomic clocks can be met by sophisticated single-mode VCSELs in the 760 to 980 nm wavelength range. Equipped with micro thermo electrical cooler (TEC) and thermistor inside a small standard TO46 package, the resulting wavelength tuning range is larger than +/- 2.5 nm. U-L-M photonics presents manufacturing aspects, device performance and reliability data on tuneable single-mode VCSELs at 760, 780, 794, 852, and 948 nm lately introduced to the market. According applications are O2 sensing, Rb pumping, Cs pumping, and moisture sensing, respectively. The first part of the paper dealing with manufacturing aspects focuses on control of resonance wavelength during epitaxial growth and process control during selective oxidation for current confinement. Acceptable resonance wavelength tolerance is as small as +/- 1nm and typical aperture size of oxide confined single-mode VCSELs is 3 μm with only few hundred nm tolerance. Both of these major production steps significantly contribute to yield on wafer values. Key performance data for the presented single-mode VCSELs are: >0.5 mW of optical output power, >30 dB side mode suppression ratio, and extrapolated 10E7 h MTTF at room temperature based on several millions of real test hours. Finally, appropriate fiber coupling solutions will be presented and discussed.
5–35 GHz broadband if amplifier section in 0.13 μm SiGe technology for W‐band heterodyne receiver RFICs

This letter presents the results of a broadband intermediate frequency (IF) section radio frequency integrated circuit designed for a W‐band heterodyne radiometer receiver in a 0.13 μm SiGe BiCMOS process. The differential IF section which consists of an amplifier and a power detector uses inductive and resistive matching to obtain a wideband response. The IF amplifier has a measured gain of 10.0–19.5 dB at 2–37 GHz, noise figure of 6–8 dB at 1–26 GHz, and OIP3 of 7–17 dBm at 1–40 GHz. The detector has a measured responsivity of 1 kV/W and an estimated noise equivalent power (NEP) of 4–6 pW/Hz1/2 at 5–35 GHz, respectively. For the IF section, the input return loss is better than 10 dB at 7–40 GHz and the responsivity is 10–82 kV/W at 5–35 GHz. The broadband properties over significantly wider bandwidths than earlier reported silicon‐based IF amplifier and power detector circuits make the SiGe 5–35 GHz IF section suitable for W‐band direct‐conversion radiometer receiver Radio Frequency Integrated Circuits with a larger predetection bandwidth and improved sensitivity. © 2015 Wiley Periodicals, Inc.

Research on Morphology Specificity of Gecko Feet at Different Scales

The fine-level structure of toes contributes to the extraordinary climbing ability of G. gecko. Research on the morphology specificity of gecko feet at different scales provides anatomical information for revealing geckos motor ability and provides theoretical basis and data which can support the development of the robot gecko feet. During the research, we used KEYENCE (VHX-600E) digital microscope system to observe and photograph the forefoot and hindfoot of G. gecko at different scales. The image processing as well as calculation of foot area and toe area was done using image processing software after the number of toe setae lamella was counted. Results: there was no significant difference between the numbers of setae lamellae on the first toes in both forefoot and hindfoot (p>0.3). The same situation also appeared in the second and forth toes. Significant difference between the numbers of the third toe setae lamella in forefoot and hindfoot was observed, the same situation also happened in the fifth toes of the forefoot and hindfoot (p<0.01), the difference between the whole area of the forefoot and hindfoot was extremely significant (p<0.005). The area of the first toe in forefoot was different from the corresponding one in hindfoot (p<0.05), while the areas of the other four toes were extremely significant from the corresponding ones in hindfoot (p<0.005). The results of the research suggest that specific designs should be adopted in the devisal of forefoot and hindfoot as well as the corresponding toes.
MIMO Wireless Networks: Channels, Techniques and Standards for Multi-Antenna, Multi-User and Multi-Cell Systems

The second edition of MIMO Wireless Networks is unique in bridging the gap between multiple-input/multiple-output (MIMO) radio propagation and signal processing techniques and presenting robust MIMO network designs for real-world wireless channels. The book emphasizes how propagation mechanisms impact MIMO system performance under practical power constraints, examining how real-world propagation affects the capacity and the error performance of MIMO transmission schemes. Combining a solid mathematical analysis with a physical and intuitive approach, the book progressively derives innovative designs, taking into consideration that MIMO channels are usually far from ideal. Reflecting developments since the first edition was published, the book has been updated and now includes several new chapters covering Multi-user MIMO, Multi-Cell MIMO, Receiver Design, MIMO in 3GPP and WiMAX and realistic system level evaluations of MIMO network performance.Reviews physical models and analytical representations of MIMO propagation channels, highlighting their strengths and weaknessesGives overview of space-time coding techniques, covering both classical and more recent schemes Shows innovative and practical designs of robust space-time coding, precoding and antenna selection techniques for realistic propagation (including single-carrier and MIMO-OFDM transmissions)
Frequency-Scanned Leaky-Wave Antenna from Negative Refractive Index Transmission Lines

A microstrip frequency-scanned leaky-wave metamaterial-based antenna is presented in this paper. It is built from two negative refraction index transmission lines fed with opposite phase using an integrated balun. The microstrip leaky-wave antenna is a two-layer structure without any vias. The antenna works well at C band from approximately 3.5 GHz to 5.5 GHz, in which the main beam scans from -40° (backfire) to 40° (endfire). As it does not include any interdigital capacitors or vias, it can be easily extended to millimeter-wave frequency bands. (4 pages)

AUTOMATIC POSITION CONTROL OF THE SOLAR CELL

: Automatic position control of the solar cell (APCoSC) is a project of the system, whose task is to direct the surface of the photovoltaic cell perpendicular to the sunrays falling on it and to follow the sun. The main parts are the base and pole, on which the cell is mounted. The base consists of a fixed part that provides a stable mounting on the ground, and a rotating part with mounted motor, which can perform a full 360 * rotation. The mast ends with a handle which, can tilt the solar panel automatically up to 90 degrees vertically by using a motor. The sun position sensor is built of 4 ambient light photosensors (APDS) arranged in the shape of a plus, enclosed in a casing, to which the sun's rays fall through the round opening. The case can be attached directly to the solar cell, or a handle using an adapter, in such a way as to form a parallel plane with the cell. The STM32 microcontroller manages the system and engine operation. The sun position sensor can work at a temperature of -30 to 85 Celsius, which ensures its universal use in many places on the earth. The photovoltaic cell produces the most energy when the sun's rays fall perpendicular to its surface, which is why the automatic tilt adjustment is used. In large cities, APCoSC is used on flat roofs of houses, where there are many obstacles such as other buildings around. The system adapts itself to the position of the sun and selects the most favourable position of the solar panel in real time.
Object-Oriented Program Tailoring Based on Model

For the redundant codes caused by software reuse and rapid development in object-oriented program, the paper proposes a cutting model and designs a cutting scheme based on this model. Firstly, a cutting model is established. Then, static analysis is made for object-oriented codes and the cutting information base of objects to be clipped is established. Lastly, the cutting information base and cutting model is matched to cut the program. A test on a practical java project indicates that the cutting scheme can make the volume of the project reduce by about 21%.
Research on Reuse-Oriented Intellectual Development Method for CNC Human-Machine Interface

To improve the productivity of HMI development, this paper proposes an intelligent development method for human-machine interface of CNC according to software reuse theory, of which the core technology consists of configurable intelligent development framework for HMI and functional component library. For the development framework, it includes customized interface editing environment, middle-layer model and automatic code generation engine. As to the design of functional component library, component object model (COM) is used to create various components which can be classified into graphic primitive components, CNC system function components, interpreter components and so on. By use of the component interface, development framework communicates with the above mentioned component and is responsible for the assembly and integration of components through which the complex HMI system is automatically generated. Based on the intelligent method, developers can realize the automatic development of human-machine interface, which will ensure product quality and improve the development efficiency.
An Investigation of Age-Related Changes in Drivers Visual Search Patterns and Driving Performance and the Relation to Tests of Basic Functional Capacities

Thirteen aged (60's) and ten young (20's) subjects performed on-the-road driving tasks. Subjects also performed psychomotor lab tasks. The road tests were: a task in which drivers voluntarily closed their eyes as much as possible; and a task in which driver's eye fixations were recorded. The lab tests were rapid tapping between targets, (motor capacity), and an embedded figures test (perceptual skill). The lab tests showed much poorer scores for the aged. On the road, aged drivers opened their eyes much longer (visual occlusion task), and had larger mean visual travel distances between fixations (degrees). The results suggested aged drivers required longer times and searched more cues to obtain adequate information. Lab and road scores were correlated. Some aged performed at the same level as younger.
Automating Convoy Training Assessment to Improve Soldier Performance

Abstract : Monitoring teams of decision-makers in complex military environments requires effective tracking of individual Soldier and team performance. An untapped source of timely and diagnostic performance information lies in ongoing communications among Soldiers operating as a team. With the right analyses the communication data can be connected to both the team's and each individual's performance, abilities and knowledge. The DARCAAT program developed and tested a toolset for automating team assessment and near real-time alarms. The toolset uses Automated Speech Recognition and Statistical Natural Language-based techniques for embedding automatic, continuous, and cumulative analysis of team communication in training and operational environments. Based on the toolset, applications were developed that apply the metrics and models to support After Action Reviews (AARs) and real-time alarms.
Use of Toxicological Data in Estimating Reference Values for Risk Assessment

A number of programs within the U.S. Environmental Protection Agency (USEPA) currently set less-than-lifetime exposure limits in addition to the chronic reference dose (RfD) and reference concentration (RfC). A review of procedures within the USEPA for setting reference values suggests that less-thanlifetime reference values should be more routinely developed and captured in the USEPA's online IRIS database where chronic RfDs and RfCs, as well as cancer slope factors, are currently available. A review of standard testing study protocols was conducted to determine what data were available for setting acute, short-term, and longer-term reference values, as well as chronic values. This review was done from the point of view of endpoints assessed for specific organ systems (both structural and functional), life stages covered by exposure and outcome, durations of exposure covered and the outcomes evaluated for each, and evaluation of latency to response and/or reversibility of effects. This review revealed a number of data gaps and research needs, including the need for an acute and/or short-term testing protocol that can be used to set acute and shortterm reference values, a strategy for when to conduct more extensive testing based on initial screening data or other information (e.g., chemical class, pharmacokinetics, mode of action), additonal standard testing guidlines protocols to allow more complete assessment of certain organ systems and life stages, development of pharmacokinetic data for different life stages, toxicity related to aging, and latency to response, particularly long-term latency as a result of developmental exposures. The implications of this review are discussed relative to characterizing hazard data for setting reference values, and the potential effects on uncertainty factors and low-dose extrapolation.
The effect of a stimulus frequency bias in side-by-side brightness ranking tests

It was found that a stimulus frequency bias can affect forced-choice brightness ranking tests and is sufficient to affect the conclusions drawn. When a stimulus is compared against a range of comparison stimuli and judgements of relative magnitude are sought, the range of comparison stimuli should be selected to enable all possible responses to be given with approximately equal frequency to avoid a stimulus frequency bias.
