Effect of Complementary Split Ring Resonator Structure on PIFA Antenna

This paper proposes a new design of Planar Inverted-F Antenna with complementary split ring resonators (CSRRs). The operating frequency of this antenna is 2.425 GHz for Wireless Local Area Network (WLAN) application. The method is to incorporate a single CSRR cell and a periodic array CSRRs on the radiating patch. We studied the effect of this method on the characteristics of antenna in free space and in the presence of the user. We used a homogeneous model of a human head near our antenna. The parameters that considered in these works are gain, electric field, magnetic field, return loss, radiation pattern, power loss density and Specific Absorption Rate. The addition of CSRRs on to PIFA antenna will improve the gain from 4.76 dB to 4.81 dB and will reduce the Specific Absorption Rate from 3.57 W/kg to 2.95 W/kg.
Managing Interest Rate Spreads in Ghana: Some Policy Discussion

This paper attempted to investigate the key determinants of high interest rate spread in Ghana and what policy measures authorities can implement to address this inherent problem facing the domestic market. The study suggested that interest rate spread in Ghana remains one of the highest when compared to peer-countries across the globe and particularly, prevailing spreads in sub-regional economies. It was further observed that real deposit rate has remained negative over the years while at the same time lending rates and other rates in the market have firmed up strongly in line with developments and trends in policy rate decisions in all segments of the loanable markets. Also, the paper revealed that high interest rate spread in Ghana is determined primarily by risk-aversion attitude of banks, the rate of inflation, the level of provision for bad debts, credit risk, exchange rate risk, cost of bank operations, scale of bank operations and finally, the level of economic activities(GDP). There is therefore the need to fashion out pragmatic policies aimed at reducing the high interest rate spread currently prevailing in the market as perceived by corporate bodies and the general business environment. Banks need to innovate and develop corporate strategies and capacities which aim at reducing their general costs of operation and other related overhead cost among others.

Evaluating the potential of radio frequency identification in emergency management

The past decade has seen numerous new applications of RFID in many domains. In the current literature today, we can also find many theory based research in Information Systems that examine factors that influence the adoption of new technology. However, there is no evidence based research in pre-adoption phase, especially in the context of emergency management. What is the potential of adopting RFID in emergency management? In order to answer this question, we conduct a multiple case study to develop an adoption framework. This framework is based on the concept of Task-technology fit. We hope that the findings of this research will not only enhance the research in technology adoption, but also assist the emergency management organizations to better plan the adoption of RFID for emergency operations.

Č Í TROUGH AS SEEN FROM POLE-DIPOLE GEOELECTRICAL MEASUREMENTS

The Hronov-Poříčí Trough represents the easternmost part of the Trutnov-Náchod Depression. The NW–SE striking structure was formed due to the post-Cretaceous flexural folding and is filled with the Upper Cretaceous sediments. Both the NE and SW margins of the trough are bounded by flexures with the Upper Cretaceous strata dipping 40–60° towards the axis of the trough. The NE flexure is situated close to the parallel Hronov-Poříčí Fault Zone. Up to now, it is not fully known, in what extent the normal faulting was involved in the evolution of the structure. From the geomorphological point of view, the normal fault constraints of the trough seem to be acceptable, as the surface topography of its present margins exhibit many signs typical for fault scarps. However, the existence of a fault system bounding all round the Hronov-Poříčí Trough has not been proved by any geological research. Hence the geophysical research was carried out on both sides of the NW part of the trough to support one of these hypothesis. Five geoelectrical profiles were measured in the area and the fault system was proved on the NE side of the trough. On the SW boundary the fault system was not found. Thus it seems, that the NE boundary is controlled by fault tectonics, whereas the SW boundary is rather formed by a simple flexure.

UvA-DARE (Digital Academic Repository) A battle for hearts and minds? Citizens’ perceptions of formal and irregular governance actors in urban Jamaica

: In cities across the world, criminal organizations have taken on many of the functions traditionally associated with the state, providing public goods such as social welfare, security and dispute resolution to the urban poor. While recent literature has begun to study the competitive and collusive relations these “irregular governance actors” have with the state, much less is known about how citizens view different governance actors. On the basis of an original survey of inner-city residents in Kingston, Jamaica, we analyze public opinion towards both formal and irregular governance actors. The results indicate that inner-city residents do not necessarily see criminal organizations and the state as competing governance structures, and that the contours of public opinion are much more complex than the literature has so far acknowledged.
The role of Transformational Leadership style on Organizational Commitment in Bahrdar city Administration Revenue office

The results have indicated that four dimensions of transformational
Creating a Python-based Portable Media Player with Enhanced Parental Control Capabilities

With the rapid development in information technology, children and adolescents have unprecedented access to digital media. Given the double-edged sword digital media has become, parents, teachers and policymakers have concerns about the negative impact that digital media exerts on children and adolescents. This leads to a growing need for digital media content regulation and censorship. However, current suppression of content in Singapore is mild and insufficient. Only a small number of films or TV shows that have explicit sensitive or offensive content were censored. A vast amount of inappropriate media content is still accessible to children and adolescents. Parents are encouraged by the MCI (Ministry of Communications and Information) to guide their children on digital media consumption. Some companies have developed computer programmes that cleanse movies containing offensive scenes. However, existing computer programmes have limited ability in allowing users to adjust the filtering levels, or generating seamless cutting results. Motivated by the above observations, we had developed a novel media player to facilitate home users, content providers and service providers to suppress content, rate and classify digital media. The software permits its user to select various degrees of content suppression according to the user’s level of acumen and discretion. Based on the properties of the sub-file objects pre-set by the user, the software will make use of its dynamic sub-file filter to examine the data set at the sub-file level for scrutiny before the substantiated content is consented for screening. With this software, user can sanitize the digital media content by skipping over specific scenes that may contain nudity, sexual situations and excessive violence, muting potentially objectionable audio words, and blurring out unsavoury objects in the scenes to preserve the integrity of the storyline. The software is also capable of preserving different categories of media classification from an unimpeded multimedia file. Unlike existing movie sanitizing tools, the software does not physically alter the original videos or make replicated copies. By applying pre-set restrictions to the video during playback, it keeps the original video unscathed.
Financial Valuation and Risk Management Working Paper No . 357 Closed-form solutions for European and Digital calls in the Hull and White stochastic volatility model and their relation to locally R-minimizing and Delta hedges

This paper derives an analytic expression for the distribution of the average volatility 1 T−t ∫ T t σ2 sds in the stochastic volatility model of Hull and White. This result answers a longstanding question, posed by Hull and White (Journal of Finance 42, 1987), whether such an analytic form exists. Our findings are applied to obtain closed-form solutions for European and Digital call option prices. The paper also provides an explicit solution for the Delta hedge of a European call. Moreover, it is proved that the Delta hedge under the minimal martingale measure coincides with the locally R-minimizing hedge in the model considered here.
Annual water, sediment, nutrient, and organic carbon fluxes in river basins: A global meta‐analysis as a function of scale

Process controls on water, sediment, nutrient, and organic carbon exports from the landscape through runoff are not fully understood. This paper provides analyses from 446 sites worldwide to evaluate the impact of environmental factors (MAP and MAT: mean annual precipitation and temperature; CLAY and BD: soil clay content and bulk density; S: slope gradient; LU: land use) on annual exports (RC: runoff coefficients; SL: sediment loads; TOCL: organic carbon losses; TNL: nitrogen losses; TPL: phosphorus losses) from different spatial scales. RC was found to increase, on average, from 18% at local scale (in headwaters), 25% at microcatchment and subcatchment scale (midreaches) to 41% at catchment scale (lower reaches of river basins) in response to multiple factors. SL increased from microplots (468 g m−2 yr−1) to plots (901 g m−2 yr−1), accompanied by decreasing TOCL and TNL. Climate was a major control masking the effects of other factors. For example, RC, SL, TOCL, TNL, and TPL tended to increase with MAP at all spatial scales. These variables, however, decreased with MAT. The impact of CLAY, BD, LU, and S on erosion variables was largely confined to the hillslope scale, where RC, SL, and TOCL decreased with CLAY, while TNL and TPL increased. The results contribute to better understanding of water, nutrient, and carbon cycles in terrestrial ecosystems and should inform river basin modeling and ecosystem management. The important role of spatial climate variability points to a need for comparative research in specific environments at nested spatiotemporal scales.
Is high-sensitivity troponin, alone or in combination with copeptin, sensitive enough for ruling out NSTEMI in very early presenters at admission? A post hoc analysis performed in emergency departments

Objectives Copeptin and high-sensitivity cardiac troponin (HS-cTn) assays improve the early detection of non-ST-segment elevation myocardial infarction (NSTEMI). Their sensitivities may, however, be reduced in very early presenters. Setting We performed a post hoc analysis of three prospective studies that included patients who presented to the emergency department for chest pain onset (CPO) of less than 6 hours. Participants 449 patients were included, in whom 12% had NSTEMI. CPO occurred <2 hours from ED presentation in 160, between 2 and 4 hours in 143 and >4 hours in 146 patients. The prevalence of NSTEMI was similar in all groups (9%, 13% and 12%, respectively, p=0.281). Measures Diagnostic performances of HS-cTn and copeptin at presentation were examined according to CPO. The discharge diagnosis was adjudicated by two experts, including cardiac troponin I (cTnI). HS-cTn and copeptin were blindly measured. Results Diagnostic accuracies of cTnI, cTnI +copeptin and HS-cardiac troponin T (HS-cTnT) (but not HS-cTnT +copeptin) lower through CPO categories. For patients with CPO <2 hours, the choice of a threshold value of 14 ng/L for HS-cTnT resulted in three false negative (Sensitivity 80%(95% CI 51% to 95%); specificity 85% (95% CI 78% to 90%); 79% of correctly ruled out patients) and that of 5 ng/L in two false negative (sensitivity 87% (95% CI 59% to 98%); specificity 58% (95% CI 50% to 66%); 52% of correctly ruled out patients). The addition of copeptin to HS-cTnT induced a decrease of misclassified patients to 1 in patients with CPO <2 hours (sensitivity 93% (95% CI 66% to 100%); specificity 41% (95% CI 33% to 50%)). Conclusion A single measurement of HS-cTn, alone or in combination with copeptin at admission, seems not safe enough for ruling out NSTEMI in very early presenters (with CPO <2 hours).

FORMULATION AND IN-VITRO EVALUATION OF NOVEL ATORVASTATIN - AMLODIPINE ORODISPERSIBLE TABLETS

The purpose of study was to fabricate rapid acting tablets for traveling, unconscious and unresponsive hypertensive patients thereby improving patient compliance, decreasing cost of the treatment and number of pills. Novel antihypertensive orodispersible tablets (ODT’s) of amlodipine and atorvastatin were prepared by direct compression and sublimation technique. Kyron T134 and Crosscaramellose sodium were used as superdisintegrant. Ten formulations (F1F10) were prepared by varying superdisintegrants concentration to optimize the best formulation. Pre-compression studies like Bulk density, Tapped density, Angle of repose, Carr’s compressibility index, Hausner’s ratio to note flow properties of powder and compatibility studies such as Fourier Transform Infrared Red spectroscopy (FTIR) and Differential Scanning Calorimetry (DSC) were performed to check any interaction between drugs and superdisintegrants. Then after flow and compressibility studies powder was compressed into ODT’s. Various features such as hardness, thickness, diameter, weight variation, friability, disintegration time, dissolution studies, wetting time, wetting volume, water absorption ratio, modified disintegration time, uniformity of contents and stability of formulated ODT’s were
THE JLAB AMPERE-CLASS CRYOMODULE CONCEPTUAL DESIGN*

For the next generation of compact high-power FELs a new cryomodule is required that is capable of accelerating up to Ampere levels of beam current. Challenges include strong HOM damping, high HOM power and high fundamental-mode power (in operating scenarios without full energy recovery). For efficient use of space a high real-estate gradient is desirable and for economic operation good fundamental-mode efficiency is important. The technology must also be robust and should be based on well-proven and reliable technologies. For Ampere-class levels of beam current both halo interception and beam break-up (BBU) are important considerations. These factors tend to drive the designs to lower frequencies where the apertures are larger and the transverse impedances are lower. To achieve these goals we propose to use a compact waveguide-damped multicell cavity packaged in an SNS-style cryomodule. CONCEPT Future high-power FEL’s for scientific, defense or industrial applications could benefit from a compact, economical and efficient accelerator layout. A small but powerful energy recovered linac (ERL) with a single high-current cryomodule could meet those requirements. The parameters for such a module are listed in table 1 and can be met using six strongly HOM damped multi-cell cavities, figure 1, in a stretched SNS-style cryomodule [1]. Experience with the JLab 10 kW FEL suggests that operating with less than 100% energy recovery is sometimes necessary so the linac cryomodule must be capable of supplying significant power to the beam.
A novel sucrose porogen‐based solid freeform fabrication system for bone scaffold manufacturing

Purpose – Musculoskeletal conditions are a major health concern in the USA because of a large aging population and increased occurrence of sport‐related injuries. Bone tissue engineering may offer a less painful alternative to traditional bone grafts with lower risk of infection. The purpose of this paper is to present a novel porogen‐based fabrication system for tissue engineering scaffolds using sucrose (C12H22O11) as the porogen building material.Design/methodology/approach – A new solid freeform fabrication system has been developed and tested, which uses pressurized extrusion to print highly biocompatible and water soluble sucrose bone scaffold porogens (or negtives). Polycaprolactone (PCL) scaffolds are manufactured by injecting molten polymer into the porogens, and the porogens are subsequently dissolved with water. The resultant scaffolds demonstrate the defined porous structure designed into the sucrose porogen manufacturing computer‐aided design model.Findings – To optimize the porogen manufactu.
A two-step initial mass function: Consequences of clustered star formation for binary properties

If stars originate in transient bound clusters of moderate size, these clusters will decay due to dynamic interactions in which a hard binary forms and ejects most or all the other stars. When the cluster members are chosen at random from a reasonable initial mass function (IMF), the resulting binary characteristics do not match current observations. We nd a signicant improvement in the trends of binary properties from this scenario when an additional constraint is taken into account, namely that there is a distribution of total cluster masses set by the masses of the cloud cores from which the clusters form. Two distinct steps then determine nal stellar masses { the choice of a cluster mass and the formation of the individual stars. We refer to this as a \two-step" IMF. Simple statistical arguments are used in this paper to show that a two-step IMF, combined with typical results from dynamic few-body system decay, tends to give better agreement between computed binary characteristics and observations than a one-step mass selection process.
An account on the assemblage of fish larvae in Ponnani estuary, South India

Estuarine environments are one of the most dynamic aquatic ecosystems and serve many important functions in coastal waters. Larval fish dynamics contribute significantly to understanding the ecology of fish populations as they can indicate the spawning-stock biomass and recruitment in adult fish stocks. Initial development stages of fishes are particularly vulnerable and are influenced by physical and biological processes. Hence the present study was aimed to characterize ichthyoplankton assemblages, to evaluate environmental influence in its structure. Ponnani backwater fish larvae assemblages displayed a clear seasonal pattern presenting higher abundances and diversities during warmer months. Throughout the year there is a wide fluctuation in salinity, temperature and primary productivity in these backwaters enabling it to be classified under stressful environment for larval forms of certain economically important marine fishes. A detailed analysis made to study the interaction of selected environmental parameters with ichthyofaunal diversity in Ponnani backwater provided a clear understanding on the influence of these variables on the distribution of marine fish larvae in the region. The results of the present analysis provided a model for the prediction of larval diversity from the prevailing environmental parameters.
