The Impact of the Calibration Method on the Accuracy of Point Clouds Derived Using Unmanned Aerial Vehicle Multi-View Stereopsis

In unmanned aerial vehicle (UAV) photogrammetric surveys, the cameracan be pre-calibrated or can be calibrated "on-the-job" using structure-from-motion anda self-calibrating bundle adjustment. This study investigates the impact on mapping accuracyof UAV photogrammetric survey blocks, the bundle adjustment and the 3D reconstructionprocess under a range of typical operating scenarios for centimetre-scale natural landformmapping (in this case, a coastal cliff). We demonstrate the sensitivity of the process tocalibration procedures and the need for careful accuracy assessment. For this investigation, vertical (nadir or near-nadir) and oblique photography were collected with 80%–90%overlap and with accurately-surveyed (σ ≤ 2 mm) and densely-distributed ground control.This allowed various scenarios to be tested and the impact on mapping accuracy to beassessed. This paper presents the results of that investigation and provides guidelines thatwill assist with operational decisions regarding camera calibration and ground control forUAV photogrammetry. The results indicate that the use of either a robust pre-calibration ora robust self-calibration results in accurate model creation from vertical-only photography,and additional oblique photography may improve the results. The results indicate thatif a dense array of high accuracy ground control points are deployed and the UAVphotography includes both vertical and oblique images, then either a pre-calibration or anon-the-job self-calibration will yield reliable models (pre-calibration RMSEXY = 7.1 mmand on-the-job self-calibration RMSEXY = 3.2 mm). When oblique photography was Remote Sens. 2015, 7 11934 excluded from the on-the-job self-calibration solution, the accuracy of the model deteriorated(by 3.3 mm horizontally and 4.7 mm vertically). When the accuracy of the ground controlwas then degraded to replicate typical operational practice (σ = 22 mm), the accuracyof the model further deteriorated (e.g., on-the-job self-calibration RMSEXY went from3.2–7.0 mm). Additionally, when the density of the ground control was reduced, the modelaccuracy also further deteriorated (e.g., on-the-job self-calibration RMSEXY went from7.0–7.3 mm). However, our results do indicate that loss of accuracy due to sparse groundcontrol can be mitigated by including oblique imagery.
Juvenile myoclonic epilepsy: A clinical and sleep EEG study

Juvenile myoclonic epilepsy (JME) is characterized by myoclonic jerks on awakening, generalized tonic--clonic seizures (GTCS) and is associated with absence seizures in more than one third of cases. Fifteen patients with juvenile myoclonic epilepsy were studied with regard to their clinical profile, EEG data and sleep EEG findings. There was a delay in the diagnosis of JME (mean of 3.5 years) due to various reasons. Sleep deprivation was the most common precipitating factor for triggering seizures, followed by fatigue. Routine EEGs were abnormal in 73.33% of cases only and had misleading findings in 6.66%. Sleep EEGs were abnormal in 100% of cases with generalized spikes, polyspikes and slow wave discharges. Discharge rates on sleep EEGs typically increased significantly during the transition phase (i.e. the asleep to awakening stage) and we consider this to be a specific finding in appropriate clinical setting. Sleep EEGs are a more sensitive and specific tool for the diagnosis of JME while routine awake EEGs may miss or mislead.
A functional architecture for scalable quantum computing

Quantum computing devices based on superconducting quantum circuits have rapidly developed in the last few years. The building blocks-superconducting qubits, quantum-limited amplifiers, and two-qubit gates-have been demonstrated by several groups. Small prototype quantum processor systems have been implemented with performance adequate to demonstrate quantum chemistry simulations, optimization algorithms, and enable experimental tests of quantum error correction schemes. A major bottleneck in the effort to develop larger systems is the need for a scalable functional architecture that combines all the core building blocks in a single, scalable technology. We describe such a functional architecture, based on a planar lattice of transmon and fluxonium qubits, parametric amplifiers, and a novel fast DC controlled two-qubit gate.
Serving Multiple Constituencies in the Business School: MBA Program vs. Research Performance

Business schools strive to meet two goals: knowledge exploration through research and knowledge exploitation through instruction. Our results indicate that research performance (pages published in leading journals) and MBA program performance (from the popular press) are different. Research performance was improved by the number of faculty, the proportion of full professors, the proportion of assistant professors, and editorships. MBA program performance was improved by the budget per faculty member, and the proportion of full professors. 1.

Problems and challenges in Human Resource Management: A case of a large organization in Pakistan

This paper critically analyzes the work culture for a mainstream financial organization operating within Pakistan, while drawing a specific example to elucidate certain dilemmas that impede the potential growth for the financial sector and its constituent workforce, besides hampering the performance of the organizations. The case study is related to an organization in financial sector which conducts a Management Trainee Program with the purpose to select, train and develop a high-potential pool of talent into future leaders and fore-runners of the organization. This paper critically analyzes several inherent problems that face the successful implementation of the trainee program under the frameworks of various theories of organizational management. To solve these problems, this article presents a detailed diagnosis of the management shortcomings to improve the firm‟s corporate culture, work ethics and employee handling strategy and mechanism. Recommendations are also made to minimize the problems and maximize the success of the Management Trainee Program in the case study organization.
On-Chip Measurement of Clock and Data Jitter With Sub-Picosecond Accuracy for 10 Gb/s Multilane CDRs

On-chip jitter measurement can be used to optimize the performance of wireline transceivers. In this work, the jitter of random data is measured on-chip by correlating the phase detector outputs from two adjacent CDR lanes. This allows the jitter's autocorrelation function to be estimated, from which the jitter's RMS value and power spectral density are extracted without using any external reference clock. The RMS value of random jitter ranging from 0.85 ps to 1.89 ps, and sinusoidal jitter from 0.89 ps to 5.1 ps is measured in PRBS31 data with less than 0.6 ps of error compared to measurements by an 80 GS/s real-time oscilloscope. Correlating the phase detectors in the CDRs with a third phase detector, which measures the phase difference between the clocks recovered by the two CDRs, allows measurement of the recovered clock jitter. Sinusoidal jitter from 1.8 ps to 5.3 ps is measured in the recovered clock with an error of less than 1 ps.
AN EMPIRICAL COMPARISON OF ZONAL, HOUSEHOLD AND PERSONAL MODELS OF HOME-BASED TRIP GENERATION

This paper reports on an empirical investigation of the alternative levels of analysis at which trip generation models may be built. The analysis of variance framework was used to quantify the loss of variation due to data aggregation preceding model-building. A comparative explanatory measure, sensitive to this loss, is proposed. On this basis, the personal level model tested was found to be the most successful in explaining the between-person variation in trip-making. While this was expected, it emphasises that a comparison of coefficients of determination could be misleading if models are built at different levels of analysis. The personal and household level models were both found to be capable of estimating zonal trip generation, the personal model tested performing marginally better. Future studies should consider the use of personal level models of home-based trip generation. (a)
Defining corporate social responsibility

Purpose – The purpose of this comparative study is to explore how large German and British companies publicly define corporate social responsibility (CSR), as well as why and how the respective notion of CSR was developed.Design/methodology/approach – The study is based on a qualitative content analysis of the CSR web sites of 40 British and German companies, and on a series of interviews with senior managers.Findings – The main findings are that CSR is now presented as a comprehensive business strategy, arising mainly from performance considerations and stakeholder pressure. Companies focus on how they interact with stakeholders and how business activities impact on society. Most CSR policies addressed community, employee and customer issues. Increasingly, “quality of life” topics are emphasised. CSR policies varied with turnover, industry sector and nationality. In developing their notions of CSR, firms emphasized the primacy of reactive pragmatism and experience. Corporate culture also emerged as an in.
Consultations for middle ear disease, antibiotic prescribing and risk factors for reattendance: a case-linked cohort study.

BACKGROUND Otitis media is the most common reason for children to receive antibiotics, but there is no evidence about the effect of prescribing on reattendance. AIM To evaluate the changing workload of middle ear disease in general practice, and the impact on surgery reattendance of prescribing antibiotics at first attendance. DESIGN OF STUDY A case-linked cohort analysis for antibiotic prescribing versus no prescribing at first consultation event. SETTING Two hundred and ninety-one practices spread throughout the UK recording for the General Practice Research Database (GPRD) and incorporating individual patient data records for 2,265,574 patients. METHOD All middle ear disease coded events that can be classed within acute otitis media (AOM) or glue ear sub-categories (and excluding chronic suppurative otitis media) were selected for analysis when the first event was from 1991-2001. The effect of antibiotic prescription on the risk of reattendance using Cox proportional hazards regression was analysed. RESULTS Total consultations for AOM have fallen markedly over this decade, and glue ear consultations have risen but by a much smaller extent (26,000 decrease versus 4000 increase in consultations per year), which makes relabelling an unlikely explanation of the fall in AOM consultations. In the 2-10 years age range, consultations for AOM fell from 105.3 to 34.7 per 1000 per year, with glue ear consultations unaltered (15.2 to 16.7 per 1000 per year). Antibiotic prescribing for AOM has stayed remarkably constant (80-84% of consultations), but antibiotic prescribing for glue ear has risen sharply (13 to 62%). Prescribing antibiotics increased the risk of reattendance for AOM (hazard ratio [HR] = 1.09, 95% confidence interval [CI] = 1.07 to 1.10) and has reduced the risk of reattendance for glue ear (HR = 0.92, 95% CI = 0.88 to 0.96). CONCLUSION Prescribing antibiotics for AOM probably increased reattendance, but the opposite effect has been noted for glue ear, which suggests a treatment effect of antibiotics in glue ear. Further research is needed to clarify whether this possible benefit is worth the known harms, and if so in which subgroups of children.
Supernova Rates: A Cosmic History

We discuss the cosmic history of supernovae on the basis of various assumptions and recent data on the star formation history. We show that supernovae rates as a function of redshift can be used to place significant constraints on progenitor models, on the star formation history, and on the importance of dust obscuration. We demonstrate that it is unlikely that the current observational indications for the existence of a cosmological constant are merely an artifact of the dominance of different progenitor classes at different redshift intervals.
A Note on Logic Programming Fixed-Point Semantics

In this paper, we present an account of classical Logic Programming fixed-point semantics in terms of two standard categorical constructions in which the least Herbrand model is characterized by properties of universality. In particular, we show that, given a program $P$, the category of models of $P$ is reflective in the category of interpretations for $P$. In addition, we show that the immediate consequence operator gives rise to an endofunctor ${T}_P$ on the category of Herbrand interpretations for $P$ such that category of algebras for ${T}_P$ is the category of Herbrand models of $P$. As consequences, we have that the least Herbrand model of $P$ is the least fixed-point of ${T}_P$ and is the reflection of the empty Herbrand interpretation.
Creating Value With Business Analytics In The Supply Chain

Business analytics (BA) systems create value and provide competitive advantage for organisations. We use the resource-based view and dynamic capabilities to develop the BA innovation process (BAIP) model, which describes how BA-enabled opportunities are introduced into organisations through a series of innovation cycles. We use the BAIP model to describe how BA-enabled opportunities were selected, justified, implemented and measured through several innovation cycles in a case study of a global wireless device distribution and supply chain provider. Several themes emerge from the case study: the importance of dynamic capabilities in maintaining competitive advantage; governance mechanisms in supporting the innovation cycles; change management when implementing the innovations; organisational learning and feedback mechanisms; measures that demonstrate the effectiveness of the innovations; and alignment of the innovations with organisational strategy.
Experimental Performance Comparison of Six-Port and Conventional Zero-IF/Low-IF Receivers for Software Defined Radio

This paper presents an experimental performance comparison among three RF architectures that are very suitable for Software Defined Radio (SDR) implementation: zero-IF, low-IF, and six-port network. A six-port receiver and a dual zero-IF/low-IF receiver have been developed for this purpose. Six-port receiver is a very promising and flexible RF architecture for the low-cost implementation of integrated microwave and millimeter-wave systems. Competitive advantages such as ultra-broadband behavior, low-cost, reconfigurability, and low power consumption, point to the six-port architecture as a good candidate to implement a SDR. However, two issues on broadband six-port receivers require intensive research: dynamic range extension, and miniaturization. In this paper, two solutions are proposed to solve these problems: the use of biased detector diodes for dynamic range extension, and the use of low temperature co-fired ceramic (LTCC) technology for six-port reduction. The measurement results indicate that the six-port receiver shows high potential benefits and advantages compared to conventional zero-IF and low-IF receivers. In addition, the capability of the six-port architecture to operate as both zero-IF and low-IF receivers has been experimentally demonstrated for the first time.
Fixation Eye Movements

In day to day events we perform complex eye movements for various different reasons, such as object recognition and during self motion. These complex motions can be observed by using eye coils [8] or eye trackers. These techniques have been used for many years in neuroscience in optic flow studies [1] and vestibular studies [9]. Eye tracking is also commonly used in nonhuman primate studies to ensure that the monkey fixates and therefore the stimulus is contained within the fovea.
A novel forward body biasing technique for subthreshold ring oscillators

In this paper, a new forward body biasing scheme is proposed for CMOS inverters used in subthreshold ring oscillators (ROs). In the proposed scheme by using auxiliary transistors higher forward body biasing voltage magnitudes are achieved compared with the conventional forward body biasing (FBB) schemes. In the literature swapped body biasing (SBB) and dynamic threshold MOSFET (DTMOS) are conventionaly used to obtain forward body biasing in the transistor. Three-stage ROs are designed for the target frequency of 13.56 MHz by using the proposed and the conventional FBB techniques in CMOS inverters. The architectures are implemented in a standard 0.18 μm CMOS technology. Post layout simulations (PLS) are performed using the Cadence Spectre simulator. The power dissipation is selected as a figure of merit (FOM) to evaluate the performances of ROs. PLS results show that with subthreshold supply voltages, the RO using the proposed forward biasing scheme consumes 451nW of power. This power dissipation is 30% less compared with SBB based RO and 48% less compared with DTMOS based RO.
Automatic disambiguation of Latin abbreviations in early modern texts for humanities digital libraries

Early modern books written in Latin contain many abbreviations of common words that are derived from earlier manuscript practice. While these abbreviations are usually easily deciphered by a reader well-versed in Latin, they pose technical problems for full text digitization: they are difficult to OCR or have typed and - if they are not expanded correctly - they limit the effectiveness of information retrieval and reading support tools in the digital library. We describe a method for the automatic expansion and disambiguation of these abbreviations.
Robust query processing

Robust query processing, a long-standing problem, is about performance, predictability and ability to avoid sudden disruptions in performance. While query optimizer being an important component of query processing, my thesis focuses on query optimizer robustness which is mainly plagued with the problem of cardinality mis-estimates. Moreover, it is well known that these mis-estimates can lead to orders of magnitude sub-optimal performance. In order to mitigate this problem, there has been considerable work in the literature such as improving quality of statistical meta-data, feedback-based adjustments, on-the-fly reoptimization of queries, etc. Most of these previous approaches are based on heuristics and do not offer worst-case performance bounds. The notable exception to the heuristics based approaches is the PlanBouquet approach which provides a provable worstcase performance guarantees. In PlanBouquet, the selectivities are not estimated but are discovered at run-time using a set (or bouquet) of plans. The PlanBouquet formulation suffers, however, from a systemic drawback - the performance bound is a function of not only the query, but also the underlying database platform. Thus the bound value becomes highly variable. Moreover, it is infeasible to compute the bound value without substantial investments in preprocessing overheads. We present SpillBound, the first algorithm for robust query processing that provides a platform-independent worst-case bound. Specifically, SpillBound delivers a worst-case multiplicative bound of D2 + 3D, where D is simply the number of errorprone predicates in the user query. Consequently, the bound value becomes independent of the optimizer and the database platform, and the guarantee can be issued just by inspecting the query without incurring any additional computational effort. Overall, SpillBound offers a new platform-independent approach to robust query processing.
Le Prix de L'argent: How (Not) to Deal With Capital Inflows

During the early 1990s much has been written about the return of foreign private capital to many of the larger Asian and Latin American countries. However, until 1992 there was little evidence that countries in sub-Saharan Africa were participating in this phenomenon. In this paper we use variance decompositions and impulse responses from vector autoregressions to shed light on the possible causes and consequences of capital inflows to four countries: Ghana, Kenya, Uganda, and Zimbabwe. We use trend-cycle decompositions to provide evidence linking the appreciation of the real exchange rate to periods of heavy capital inflows. We show that domestic real interest rates have played an important role in explaining the recent behavior of the real exchange rate. In particular, we trace the rise in domestic nominal and real interest rates to policies designed to liberalize the domestic financial sector and attempts to curb the monetary expansion associated with the capital inflows through sterilized intervention.

Identification of P-Glycoprotein and Transport Mechanism of Paclitaxel in Syncytiotrophoblast Cells

When chemotherapy is administered during pregnancy, it is important to consider the fetus chemotherapy exposure, because it may lead to fetal consequences. Paclitaxel has become widely used in the metastatic and adjuvant settings for woman with cancer including breast and ovarian cancer. Therefore, we attempted to clarify the transport mechanisms of paclitaxel through blood-placenta barrier using rat conditionally immortalized syncytiotrophoblast cell lines (TR-TBTs). The uptake of paclitaxel was time- and temperature-dependent. Paclitaxel was eliminated about 50% from the cells within 30 min. The uptake of paclitaxel was saturable with Km of 168 μM and 371 μM in TR-TBT 18d-1 and TR-TBT 18d-2, respectively. [3H]Paclitaxel uptake was markedly inhibited by cyclosporine and verapamil, well-known substrates of P-glycoprotein (P-gp) transporter. However, several MRP substrates and organic anions had no effect on [3H]paclitaxel uptake in TR-TBT cells. These results suggest that P-gp may be involved in paclitaxel transport at the placenta. TR-TBT cells expressed mRNA of P-gp. These findings are important for therapy of breast and ovarian cancer of pregnant women, and should be useful data in elucidating teratogenicity of paclitaxel during pregnancy.
A Cooperative Approach for Opportunistic Routing In Mobile Ad Hoc Networks

Cooperative Communication, a new research area, has revealed a recent origin in the wireless networks, which combines the link-quality and the broadcasting nature of the wireless channels. It is a pure network layer scheme that can be built on top of the wireless networking equipment. Nodes in the network use a lightweight proactive source routing protocol to determine a list of intermediate nodes that the data packets should follow en route to the destination. Here, when a data packet is broadcast by an upstream node and received by a downstream node further along the route, it continues its way from there and thus will arrive at the destination node sooner. This is achieved through cooperative data communication at the link and network layers. The CORMAN protocol was used for the purpose of cooperative communication, is implemented and observed significant performance improvement in varying mobile settings.
