Risk factors of failure in start-up textile enterprises

Despite various attempts made to curb the import of textile and clothing products from China, the demand for Chinese textile products and garments in Tshwane is quite high. Start-up enterprises operating in the textile industry of Gauteng Province in South Africa depend extensively on merchandise imported from China. The research was based on a five-yearlong study conducted by Marivate [2014. “The Impact of Entrepreneurial Skills on the Viability and Long-term Survival of Small Businesses: A case of the City of Tshwane, South Africa. European. ” Journal of Business, Economics and Accountancy 2 (2): 53–72] by collecting data from a cohort of 312 textile enterprises operating in the City of Tshwane. The aim of study was to construct a survival probability model for the enterprises in the study as a means of identifying the most significant risk factor for failure in start-up textile enterprises. A semi-parametric survival model was used for identifying key risk factors for failure. The study found that about 51% of start-up businesses were viable at the end of the study period. The key determinants of survival and profitability were the ability to order merchandise in bulk on credit from wholesale Chinese suppliers, access to a trusted trading partner in China, ‘Guanxi’, and the attendance of at least one training session on entrepreneurial skills. Based on findings obtained from the study, there is no basis for recommending the elimination of low-wage employment in the textile and clothing industry of Tshwane.
Music performance by discovering community loops

Technologies for discovering sounds in large databases can help breaking the boundary between exploration and music performance. In this paper, we present a system for exploring loops from Freesound. Sound files are grouped by their most common repetition periods, so that they can be played in sync. A graph layout algorithm is used to organize sounds in a two-dimensional plane so that loops with similar timbre are spatially close. The result is a system that can be used as a musical instrument: since sounds will always play in sync, the user can freely explore the variety of sounds uploaded by the Freesound community, while continuously producing a rhythmic music stream.
Co-designing Blockchain and Market in the Dutch Electricity Sector: Creating a conceptual market design for the Dutch intraday market based on the effects of blockchain facilitated data coordination

Blockchain technology provides new methods of value transferring and data coordination, which could potentially benefit the changing management needs for the Dutch electricity sector. However, little research is done on how such a blockchain should be implemented and how it could best cooperate with the electricity markets. The goal of this report is thus to identify market design interventions that will best facilitate blockchain in the Dutch electricity sector. To reach this goal, three phases are performed; literature and stakeholder analysis for use case research, transaction cost theory application for use case selection, and a design process to redesign and evaluate the Dutch intraday electricity market. The conclusion of the design process is that the currently functional intraday market design would work best in cooperation with a data coordination blockchain, which shares bidding information between traders. The data coordination blockchain would in this case provide only limited added benefit over conventional data sharing systems, but could provide a valuable first step towards the implementation of more elaborate blockchain systems in the electricity sector.
Graph regularized GM-pLSA with application to video classification

Seeing that standard probabilistic Latent Semantic Analysis (pLSA) only handles discrete quantity, pLSA with Gaussian Mixtures (GM-pLSA) is proposed to extend it to continuous feature space by using Gaussian Mixture Model (GMM) to describe the feature distribution under each aspect. However, inheriting from standard pLSA, GM-pLSA still assumes that terms are independent and ignores the intrinsic correlations between them. In this paper, we present a graph regularized GM-pLSA (GRGM-pLSA) model as an extension of GM-pLSA to take advantage of this neglected term correlation information for performance improvement. Appealing to the manifold learning theory, such a useful clue is captured by a graph regularizer and embedded into the process of model learning. In the application of video classification, two kinds of term correlation respectively representing temporal consistency and visual similarity between sub-shots are evaluated. Experimental results show that our proposed GRGM-pLSA outperforms GM-pLSA.
Solving the unimolecular master equation with a weighted subspace projection method

A weighted subspace projection method for solving the unimolecular master equation over a wide range of temperatures and pressures is developed. Sample calculations modeling the dissociation of ethane at 300 K and pressures as low as 0.65 Torr demonstrates the utility of the method in regimes where standard projection methods fail. For the sample calculations the weighted Arnoldi method was able to reliably calculate the smallest eigenvalue of the rate matrix in excellent agreement with calculations using the Nesbet algorithm. Extremely small eigenvalues of the order of −10−48 could be calculated without difficulty. The formal equivalence between various weighting schemes and common matrix transformations is shown. The point that merely taking the transpose of the rate matrix can be extremely beneficial is made, commenting on the relationship between the left and right eigenvectors of the rate matrix. © 2000 John Wiley & Sons, Inc.

Water consumption pattern in the traditional villas of Abu Dhabi

The municipal water consumption in the Emirate of Abu Dhabi, United Arab Emirates, is extremely high (565 to 920 litre per capita per day (lpcd)), despite of their limited water resources. The residential activities account for about 52% of their expensive desalinated water. In 2013, the total available desalinated water in the Abu Dhabi was about 244,666 million imperial gallons. This high residential water consumption is driven by their high indoor and outdoor water end uses. It was informed by the water authorities that the residential water consumption rates in the Abu Dhabi are particularly high in the traditional villa type detached houses. This study investigated the pattern of water consumptions in medium sized villas and identified the factors affecting their water consumption. The water meter reading data for a consecutive 12 month period were collected from 100 villas located in a residential compound in Abu Dhabi. All villas are uniform in their plot (2050 m2) and building (750 m2) sizes. The villas are connected to the water distribution system by a service connection pipe (Medium Density Polyethylene) of diameter 20 mm, except three villas that have two service connection pipes. In order to verify the collected meter reading data from individual villas, the district area meter (DAM) reading was also collected for the same period. It was found that the supplied water (DAM reading) was approximately 5% more than the accumulated water consumption in all villas. This additional water was used for network flushing, fire demand and lines losses. The average monthly sewer flow (wastewater volume) from all villas were also collected. After collection of the number of people information on villas, it was found that the average per capita water consumption rate is more than 2500 lpcd. The summer (May –August) consumption was found about 5% more than that of other months. The average indoor water consumption rate was estimated approximately 350 lpcd. The regression analysis confirmed that water consumption in the villas is not significantly dependent on the number of people live in villas, which is attributable to the fact that about 85% of water are used for outdoor activities (plantation, car washing, etc.). Finally, it was recommended to reduce the outdoor water consumption by introducing alternative water sources such as the treated sewage effluent and the treated greywater.
A MODIFIED PROJECTIVE TRANSFORMATION SCHEME FOR MOSAICKING MULTI-CAMERA IMAGING SYSTEM EQUIPPED ON A LARGE PAYLOAD FIXED- WING UAS

In recent years, Unmanned Aerial System (UAS) has been applied to collect aerial images for mapping, disaster investigation, vegetation monitoring and etc. It is a higher mobility and lower risk platform for human operation, but the low payload and short operation time reduce the image collection efficiency. In this study, one nadir and four oblique consumer grade DSLR cameras composed multiple camera system is equipped on a large payload UAS, which is designed to collect large ground coverage images in an effective way. The field of view (FOV) is increased to 127 degree, which is thus suitable to collect disaster images in mountainous area. The synthetic acquired five images are registered and mosaicked as larger format virtual image for reducing the number of images, post processing time, and for easier stereo plotting. Instead of traditional image matching and applying bundle adjustment method to estimate transformation parameters, the IOPs and ROPs of multiple cameras are calibrated and derived the coefficients of modified projective transformation (MPT) model for image mosaicking. However, there are some uncertainty of indoor calibrated IOPs and ROPs since the different environment conditions as well as the vibration of UAS, which will cause misregistration effect of initial MPT results. Remaining residuals are analysed through tie points matching on overlapping area of initial MPT results, in which displacement and scale difference are introduced and corrected to modify the ROPs and IOPs for finer registration results. In this experiment, the internal accuracy of mosaic image is better than 0.5 pixels after correcting the systematic errors. Comparison between separate cameras and mosaic images through rigorous aerial triangulation are conducted, in which the RMSE of 5 control and 9 check points is less than 5 cm and 10 cm in planimetric and vertical directions, respectively, for all cases. It proves that the designed imaging system and the proposed scheme have potential to create large scale topographic map.
Peak Electromyographic Activity and Jaw-Closing Force in Man

In previous experiments we have used a digital filtering technique to estimate the onset, duration, and peak activity of electromyographic signals from the jaw muscles. This technique produces smooth, measurable signals, with little error in the definition of the peak response. The delay between the peak electromyographic activity in separate jaw elevator muscles and the total clenching force produced by their isometric contraction has been estimated,,to be between 50 and 80 msec (AHLGREN and OWALL, Arch Oral Biol 15: 271-280, 1970). Measurements made on isolated muscles under isometric conditions in cineplastic amputees have suggested delays of 80 msec (,D +420) between peak electrical activity and peak tension (INMAN ET AL, Electroencephlogr Clin Neurophysiol 4:187-194, 1952). In both studies, analogue devices were used to provide smoothed muscle signals. The aim of the present study was to measure the lag between the peak electrical events in the anterior temporal muscle and jaw-closing force by means of a digital smoothing technique. Electrical activity in the right anterior temporal muscle was recorded by means of bipolar surface electrodes and a suitable amplifier.a The signals were sampled every millisecond for one second by the A-D converter of a disc-based 12K minicomputer.b At the same time, the computer sampled the output of a strain-gauge amplifier,c which provided a signal from a linear force transducer held between the upper and lower right canine teeth. The transducer consisted of two flat, notched, brass beams each 2-mm thick. These were separated by 2 mm, and one carried two foil strain gauges. In this way the isometric biting force was measured, the canine teeth being in an edge-to-edge, but separated, rela-

The measurement system is described and the results of the experimental validation of the developed algorithms are depicted.
Frequency spectrum of NH bonds in eglin c from spectral density mapping at multiple fields.

The internal mobility of the protein eglin c is characterized with spectral density functions of the NH vectors obtained from heteronuclear NMR relaxation at multiple field strengths (7.04, 11.74, and 14.1 T). The spectral density functions, J(omega), describe the frequency spectrum of the rotational fluctuations of the XH bond vectors (15N-1H and 13C-1H). The spectral density-mapping approach [Peng, J. W. , & Wagner, G. (1992a) J. Magn. Reson. 98, 308-332; Peng, J. W. , & Wagner, G (1992b) Biochemistry 31, 8571-8586] permits the direct evaluation of J(omega) at the five frequencies 0, omega N, magnitude of omega H - magnitude of omega X, omega H, and magnitude of omega H + magnitude of omega X. The 15N-1H relaxation measurements from three field strengths on 15N-enriched eglin c resulted in 18 relaxation rate constants per NH bond and 13 unique evaluations of each NH spectral density function. Dynamic heterogeneity along the protein backbone is manifested most clearly in spectral density values at lower frequencies (< 100 MHz). The effective value of J(0), J(eff)(0), is the most sensitive probe of dynamics as it is affected by both rapid internal motions and slow chemical exchange processes. Low J(eff)(0) and J(omega N) values are correlated with fast amide proton-deuteron exchange rates; the converse, however, is not observed. Anomalies in J(omega H) and J(magnitude of omega H +/- magnitude of omega N) observed in the first applications of the spectral-mapping approach are now attributable to the high sensitivity of these values to small errors in the rate constants. These anomalies can be reduced by the use of a reduced spectral-mapping procedure. The use of multiple field strengths allows the identification of slow exchange processes manifested as an increase of J(eff)(0) with spectrometer field strength.

Transient Versus Sustained Phosphorylation and Nuclear Accumulation of ERKs Underlie Anti-Versus Pro-apoptotic Effects of Estrogens*

Sex steroids exert anti-apoptotic effects on osteoblasts/osteocytes but exert pro-apoptotic effects on osteoclasts, in both cases requiring activation of the extracellular signal-regulated kinases (ERKs). To explain the mechanistic basis of this divergence, we searched for differences in the kinetics of phosphorylation and/or in the subcellular localization of ERKs in response to 17β-estradiol in the two cell types. In contrast to its transient effect on ERK phosphorylation in osteocytic cells (return to base line by 30 min), 17β-estradiol-induced ERK phosphorylation in osteoclasts was sustained for at least 24 h following exposure to the hormone. Conversion of sustained ERK phosphorylation to transient, by means of cholera toxin-induced activation of the adenylate cyclase/cAMP/protein kinase A pathway, abrogated the pro-apoptotic effect of 17β-estradiol on osteoclasts. Conversely, prolongation of ERK activation in osteocytes, by means of leptomycin B-induced inhibition of ERK export from the nucleus or overexpression of a green fluorescent protein-ERK2 mutant that resides permanently in the nucleus, converted the anti-apoptotic effect of 17β-estradiol to a pro-apoptotic one. These findings indicate that the kinetics of ERK phosphorylation and the length of time that phospho-ERKs are retained in the nucleus are responsible for pro-versus anti-apoptotic effects of estrogen on different cell types of bone and perhaps their many other target tissues.
Touching and Interacting with Inaccessible Cultural Heritage

The sense of touch provides a particular access to our environment, enabling a tangible relation with it. In the particular case of cultural heritage, touching the past, apart from being a universal dream, can provide essential information to analyze, understand, or restore artifacts. However, archaeological objects cannot always offer tangible access, either because they have been destroyed or are too damaged, or because they are part of a larger assembly. In other cases, it is the context of use that has become inaccessible, as it is related to an outdated activity. We propose a workflow based on a combination of computed tomography, 3D images, and 3D printing to provide concrete access to cultural heritage, and we illustrate this workflow in different contexts of inaccessibility. These technologies are already used in cultural heritage, but seldom combined, and are most often employed for exceptional artifacts. We propose to combine these technologies in case studies corresponding to relevant archaeological situations.
Realistic paint simulation based on fluidity, diffusion, and absorption

We present a new method to create realistic paint simulation, utilizing the characteristics of paint, such as fluidity, diffusion, and absorption. We treat the painting elements separately as pigment, binder, solvent, and paper. Adopting smoothed‐particle hydrodynamics including a consideration of viscoelastic movement, we simulate the fluid motion of the paint and the solvent. To handle the diffusion of the pigment in the solvent, we utilize the mass transfer method. Following Fick's law, the concentration of pigment changes and each pigment particle is diffused to the neighborhood accordingly. As time elapses, the binder and the solvent are absorbed, and for the most part, the pigment remains on the paper. The Lucas–Washburn equation determines the distance of absorption. The examples show that our approach can effectively generate various types of painting. Copyright © 2013 John Wiley & Sons, Ltd.
