Performance of Low-Order Polynomial Interpolators in the Presence of Oversampled Input

this paper compares the signal-to-noise ratio performance of several polynomial interpolator algorithms. Signal-to-noise analysis is extended to the improvement thereof as the input signal is ideally oversampled. The algorithms considered are drop-sample, linear, third-order Lagrange, Hermite, second-order osculating, and Bspline. The analysis reveals an interesting performance trade-off between signal-to-noise ratio and passband flatness. Motivation Interpolation is the method by which a function of known value at a sample of points is approximated at an unknown value of the independent variable, which, in audio signal processing, is often time. The points chosen for interpolation are the ones in closest proximity to the target time value. Interpolation employs the time values of the known points relative to the unknown point to calculate weights. The interpolated result is the dot product of the chosen points and the calculated weights. Polynomial interpolation uses polynomials of the time variable to determine the weights. Its principal advantage over table-lookup interpolation is that the time variable resolution of the interpolation function is arbitrary, whereas the resolution of table-lookup is restricted to the size of the table. Two widely employed interpolation methods, drop-sample and linear, fall into the zeroth and first order classes, respectively, of polynomial interpolators. For the application of audio signal resampling, the source to interpolate employs a constant sampling interval. The spectrum of this sampled signal has a periodicity of the sampling frequency. An interpolator acts as a (theoretically) continuous filter to convert the sampled source to a continuous signal, from which samples can be taken at the desired sampling interval. Therefore, an interpolator must be judged on how good a lowpass filter the continuous representation of the system becomes. Ideally, all frequencies beyond the Nyquist frequency, or aliasing frequencies, should be completely attenuated. However, no convolution with a function of finite length can attain this ideal frequency response. A good performance metric integrates the frequency response power over the passband, from negative to positive Nyquist, and the power over all other frequencies to attain a signal-to-noise ratio.
ISO 9000 and TQM: substitutes or complementaries?

After analysing a sample of 442 of the Spanish biggest manufacturing companies, some evidence about the influence of total quality management (TQM) on the companies’ operating performance has been obtained. However, companies applying TQM together with the ISO 9000 standards did not show positive results. This fact leads to the consideration that, despite the beliefs about ISO 9000 as a good first step in the way of implementing TQM, once implemented, some of the ISO 9000 principles are contradictory with TQM philosophy. These not congruent systems applied together would drive the company to obtain less benefits than the use of only one of them. The study concludes that when ISO 9000 and TQM are applied simultaneously, the resultant benefits to the company are not better than those experienced if either system were applied in isolation.

A revised branch-and-price algorithm for dial-a-ride problems with the consideration of time-dependent travel cost

Summary Developing demand responsive transit systems are important with regard to meeting the travel needs for elderly people. Although Dial-a-ride Problems (DARP) have been discussed for several decades, most researchers have worked to develop algorithms with low computational cost under the minimal total travel costs, and fewer studies have considered how changes in travel time might affect the vehicle routes and service sequences. Ignoring such variations in travel time when design vehicle routes and schedules might lead to the production of inefficient vehicle routes, as well as incorrect actual vehicle arrival times at the related nodes. The purpose of this paper is to construct a DARP formulation with consideration of time-dependent travel times and utilizes the traffic simulation software, DynaTAIWAN, to simulate the real traffic conditions in order to obtain the time-dependent travel time matrices. The branch-and-price approach is introduced for the time-dependent DARP and tested by examining the sub-network of Kaohsiung City, Taiwan. The numerical results reveal that the length of the time window can significantly affect the vehicle routes and quantitative measurements. As the length of the time window increases, the objective value and the number of vehicles will reduce significantly. However, the CPU time, the average pickup delay time, the average delivery delay time and the average actual ride time (ART)/direct ride time (DRT) will increase significantly as the length of the time window increases. Designing the vehicle routes to reduce operating costs and satisfy the requirements of customers is a difficult task, and a trade-off must be made between these goals.

Single-phase power factor correction circuit with three-level boost converter

A control scheme for the single-phase three-level rectifier with high power factor and low total harmonic distortion of the line current is proposed. A hysteresis current comparator is used to control the line current following the line current command. The advantages of the proposed control scheme for a three-level rectifier are (1) low blocking voltage of each power device; (2) low harmonic content; and (3) high power factor. The control scheme is based on the region detector of the rectified line voltage, capacitor compensator and hysteresis current comparator. Experimental results from a laboratory prototype show that the proposed scheme gives good steady-state performance of the three-level rectifier which coincides with the theoretical results.

Effects of hydrogen loading and grating strength on the thermal stability of fiber Bragg gratings

Summary form only given. We have demonstrated that gratings of different strengths in unhydrogenated fiber display different stabilities at elevated temperatures, however, gratings written in hydrogenated fiber did not show this trend. These observations should provide further insight into the mechanism of photo-induced index change during both writing and annealing.

In-vehicle signing functions and systems concepts

This paper describes functional requirements and system concepts for an In-Vehicle Signing (IVS) system, which will bring information from roadway signs, signals, and pavement markings into the vehicle for presentation to the driver. Information filter functions will assure that the only messages displayed are those which are important to the driver and which apply. Display functions will optimize the presentation of the message to ambient conditions, driver preferences, the number of simultaneous messages, and the urgency of the message. Timing functions will display a sign as soon as it is needed, for the entire time that it applies, and only while it applies. IVS is one of the core components of an integrated In-Vehicle Information System, which will manage and fuse all driving-related information. Two different IVS system concepts have been investigated: one based on a map database, the other on beacon technology. This work is being conducted by the Oak Ridge National Laboratory for the US Federal Highway Administration as part of the Intelligent Transportation System Program.

To be or to become? : an enquiry into the changing nature of requirements in open source health IT

This thesis develops a contemporary problematisation of software requirements. It departs from traditional conceptions of requirements as simple, tamed objects with deterministic force over socio-technical actors and based on assumptions of stability. Such views can lead to a narrow, ultimately unfruitful understanding of the significance of requirements and denied wider consequences of their modes of articulation. Instead, the thesis builds on perspectives where requirements are complex and interactive actors. The thesis uses openEHR—an open source health IT project aiming to build interoperable Electronic Health Records (EHRs)—as a case study. Studying open source practice offers a good opportunity to consider the nature of requirements because there is an ongoing debate about requirements’ role and influence on development activities and project organisation. The analysis uses Deleuzian concepts of assemblage, multiplicity and becoming. These themes align with a larger body of work influenced by STS and process oriented theorisations, which see the world as dynamic and performative. The philosophy of Deleuze and Guattari in particular provides a counter-balance to any assumed stability in the world. The thesis presents a new account of the nature of requirements, one that reflects their complex entanglement within software development and open source in particular. Requirements are not insipid descriptive statements that abstract and simplify the world deterministically. They have an intricate existence which serves to hold the potential in the assemblage to become many things. In particular, requirements insinuate themselves into a project’s identity, guide a project through territories—some to be explored, some to be disregarded—and demand specific ways to be recognised, engaged, and cared for. The thesis argues that requirements are more virtual than originally thought, having a subtle, not necessarily visible influence on their assemblages and the way socio-technical actors can potentially relate to the project itself.
Assessing the effectiveness of static code analysis

For complex systems identifying and mitigating a gap between suppliers' provided software and customer certification needs is difficult. Getting it wrong can cause program delays or even project failure. A mitigation strategy is to carry out additional assurance analysis such as Static Code Analysis (SCA). This can add significantly to the procurement expense and may require repeating with new software upgrades. The purpose of this paper is to present an analysis of the effectiveness of nearly 10 years efforts of additional independent SCA assurance on a large software intensive project. The evidence presented will also be supported by SCA findings on other projects conducting additional SCA. The analysis work was carried out for a Ministry of Defence Integrated Project Team as part of their continual assessment and improvement of safety.
Survey on Identification of Alzheimer Disease Using Magnetic Resonance Imaging (MRI) Images

Alzheimer’s disease (AD) is a neuro-degenerative disorder which is characterised functional and cognitive deficits that take place progressively. Early detection of the AD is important for the therapy to be early and this may slow down the disease and its progression. For the purpose of bringing about an improvement to the incidence of early detection of the AD, there may be certain Normal Controls (NC) that is based on the structural analysis of Magnetic Resonance Imaging (MRI). In fact, an early detection of the AD by means of using an MRI can help both patients, as well as physicians, to a great extent since it is of a low cost and is also a procedure that is non-invasive providing objective diagnosis by avoiding human errors. This has been connected to the accumulation of the amyloid and the tau proteins found in the brain which is probably the commonest cause for a case of dementia and also accounts for almost 70% of cases of dementia. The MRI is an extremely promising technique in terms of detection of functional or structural brain differences observed among both these patient populations. For the purpose of this work, there had been a new survey that had been made for the identification of a new case of Alzheimer’s disease by means of using the MRI images.
Dry eye, Contact lenses and Preservatives in Glaucoma Medication

Current review focus on hidden links between glaucoma, contact lenses and Ocular Surface Disease (OSD), in glaucoma the most important treatment is the control of progression through targeted pharmaceutical protection, keeping low intraocular pressure, by prescribing ophthalmic medications. On the other hand, use of preservatives in glaucoma medications is a common practice in order to maintain their effectiveness for an extended period of time. Anti-glaucoma medications enclose preservatives and the 70% of them contain a very common preserving agent, the Benzalkonium chloride (BAK). In glaucoma medications BAK toxicity includes, loss of tear film stability, direct damages to the cornea and conjunctival epithelium, and possible immune allergic reactions. Other types of preservatives may exhibit less toxicity but are still irritating agents. Of course, concentration and duration of treatment determine the extent of side effects of the preservatives. High content hydrogel contact lenses absorb BAK molecules and release them slowly onto the corneal epithelium over time. So, patients that use contact lenses may wear those better 15 minutes after the medication. The prolonged exposure to BAK is well known to increase symptoms of ocular inflammation. A diminish of patient's life quality is observed and patient compliance to the specific anti-glaucoma medication, is also undermined. Conversely, there are more causes of dry eye in glaucoma patients, as the majority of the glaucomatous patients are elderly. Such factor is the decrease of tear production with increasing of age and numerous changes in the composition of the tear film. At the same time, elderly often suffer from other pathological diseases that encourage the development of dry eye and eye irritations. Adding the anti-glaucoma eye drops containing preservatives along with the constant use of contact lenses, we are led to a serious multifactorial dry eye condition. The last years several antiglaucoma agents have been marketed such as preservative-free or Benzalkonium chloride-free formulations in an attempt to reduce the side effects related to the preservatives.
Cold-inducible RNA-binding protein migrates from the nucleus to the cytoplasm under cold stress in normal human bronchial epithelial cells via TRPM8-mediated mechanism

Background Cold-inducible RNA-binding protein (CIRP or hnRNP A18) is a multifunctional stress-responsive protein. Our previous study demonstrated that cold stress increased CIRP expression and migrated from the nucleus to the cytoplasm in airway epithelial cells. However, the mechanism through which CIRP migrates from the nucleus to the cytoplasm upon cold stress remains unknown. Methods The expression of CIRP in the bronchial epithelium was examined using immunofluorescence, real-time polymerase chain reaction (RT-PCR), and Western blotting. The expression of inflammatory factors interleukin-1β (IL-1β), interleukin-6 (IL-6), interleukin-8 (IL-8), and tumor necrosis factor-α (TNF-α) were detected by ELISA and RT-PCR. Transient receptor potential melastatin 8 (TRPM8) receptor function was characterized by Ca2+ imaging. Results Cold stress upregulated the expression of CIRP, inflammatory factors and promoted the translocation of CIRP from the nucleus to the cytoplasm in normal human bronchial epithelial (NHBE) cells. Cold stress activated the TRPM8/(Ca2+)/PKCα/glycogen synthase kinase 3β (GSK3β) signaling cascade, and that inhibition of this signaling pathway attenuated the migration of CIRP from the nucleus to cytoplasm but did not decrease its overexpression induced by cold stress. Knocked down CIRP expression or blocked CIRP migration between the nucleus and cytoplasm significantly decreased inflammatory factor expression. Conclusions These results indicate that cold stress leads to the migration of CIRP from the nucleus to the cytoplasm with alteration of expression, which are involved in the expression of inflammatory factors (IL-1β, IL-6, IL-8 and TNF-α) induced by cold air, through TRPM8/Ca2+/PKCα/GSK3β signaling cascade.
