Advance Control and Monitoring of Daily Electricity Consumption Using a Smart Energy Detective (2010)

This paper presents application of GSM–SMS technology for real time data acquisition. The application is based on a field data collection prototype system that is composed of field monitoring and host control platforms. Advancement in technology has given rise to exploring ways of advancing control of devices beyond the environment in which it is been operated. This is the essence of this research. This monitoring system consist of a new energy calculation algorithm, offering electricity packages with a intelligent monitoring system for daily power consumption connected to base-station via GSM network. The proposed algorithm will be an affective monitoring tool for energy supplier companies in Malaysia also helping them to produce a better awareness among users about energy consumption.

An examination on effective auditory stimulation when grasping a virtual object with a bare hand (2018)

We have been developed an augmented reality (AR) system that gives pseudo-haptic feedback when a user grasps a virtual object with a bare hand. In previous studies, pseudo-haptic feedback was emphasized by adding an auditory stimulus to visual information. However, the effective way of presenting the auditory stimulus has not been studied. Therefore, we investigate the type and presenting method of effective auditory stimulus that gives pseudo-haptic feedback.
Synthesis and Structure of Zirconium and Hafnium Polymerisation Catalysts Stabilised by Very Bulky Aminopyridinato Ligands (2008)

Abstract Mono(aminopyridinato) complexes of the type [ApM(CH 2 C 6 H 5 ) 3 ] [M = Zr, Hf and Ap = aminopyridinate] were prepared by treating the three different sterically demanding aminopyridines with one equiv. of tetrabenzylzirconium or ‐hafnium. One of the three benzyl groups is η 2 ‐coordinated in the solid state. However all of the three benzyl substituents are equivalent in solution as evidenced by the 1 H NMR spectrum. Treatment of these neutral complexes with B(C 6 F 5 ) 3 afforded the corresponding zwitterionic dibenzyl complexes. The η 6 ‐coordination of the phenyl ring of the B‐bound benzyl group to the metal centre was supported by 1 H NMR spectroscopy and confirmed by single‐crystal X‐ray diffraction analysis. These zwitterionic complexes show very low activity for ethylene polymerisation at low temperature since the coordination site is blocked by the η 6 ‐coordinated phenyl ring. At elevated temperature, moderate activity with the formation of high molecular weight polyethylene (PE) was observed. An attempted abstraction of the second benzyl group failed when the zwitterionic complexes were treated with an additional equivalent of B(C 6 F 5 ) 3 . Using one equiv. of [R 2 (Me)NH][B(C 6 F 5 ) 4 ] (R = C 16 H 33 –C 18 H 37 ) instead of B(C 6 F 5 ) 3 , moderate activities of ethylene polymerisation were observed. Treatment of the aminopyridinato metal tribenzyls with [R 2 (Me)NH][B(C 6 F 5 ) 4 ] (R = C 16 H 33 –C 18 H 37 ) gave active ethylene polymerisation catalysts which produced low molecular weight PE in the case of the zirconium analogues and higher molecular weight PE in the case of the hafnium example. Propylene homopolymerisation under the same conditions failed. Ethylene–propylene copolymers with separated propene units and alternating sequences were observed in the presence of both monomers.(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
A Review of Fault Diagnosis for Traction Induction Motor (2018)

With the rapid development of traction motor, the mechanical health monitoring and fault diagnosis field have entered the era of big data. Definite harmonic signals of the line current are located by a popular method known as motor current signature analysis. Different faults of an induction motor such as rotor, stator, bearing, vibration, air gap eccentricity and their different diagnosis techniques are also explored. In fact, the actual fault detection also has a deep development in the artificial intelligence. It is truly evident that the scope of this area is vast. Hence, acknowledging the need for future research, this review paper presents a birds eye view on different types of traction induction faults and their diagnostics schemes.
Controlling morpholino experiments: don't stop making antisense (2008)

One of the most significant problems facing developmental biologists who do not work on an organism with well-developed genetics - and even for some who do - is how to inhibit the action of a gene of interest during development so as to learn about its normal biological function. A widely adopted approach is to use antisense technologies, and especially morpholino antisense oligonucleotides. In this article, we review the use of such reagents and present examples of how they have provided insights into developmental mechanisms. We also discuss how the use of morpholinos can lead to misleading results, including off-target effects, and we suggest controls that will allow researchers to interpret morpholino experiments correctly.
Policy-agile encrypted networks via secure function computation (2010)

Recent developments in cryptography in the areas of secure multi-party function computation and homomorphic encryption enable new policy-agile encrypted networking capabilities. By applying algorithms that can securely perform encrypted operations on encrypted data without decryption of either, context- and content-aware decisions can be performed (or policy rules applied) within a new advanced “black core” network while preserving confidentiality of the mission context and content. We discuss three application areas-with applicability to defense, law enforcement, intelligence community, and commercial networks, especially when resource sharing and collaboration across multiple organizations must occur over out-sourced third party infrastructures-that are enabled.
Crohn's-Like Complications in Patients With Ulcerative Colitis After Total Proctocolectomy and Ileal Pouch-Anal Anastomosis (1997)

Total proctocolectomy with ileal pouch-anal anastomosis (IPAA) has become an established surgical procedure for ulcerative colitis. Occasional patients who have undergone IPAA develop persistent or recurrent episodes of pouchitis (chronic pouchitis), from which a subset also develop gastrointestinal and systemic complications that are identical to those seen in Crohn's disease. These complications include enteric stenoses or fistulas in the pouch or pouch inlet segment, perianal fistulas or abscesses, pouch fistulas, arthritis, iridocyclitis, and pyoderma gangrenosum. The development of Crohn's-like gastrointestinal complications in a patient with chronic pouchitis frequently engenders concern that the pathologist misinterpreted the proctocolectomy specimen as ulcerative colitis instead of Crohn's disease. We describe eight patients who developed chronic pouchitis and Crohn's-like complications after IPAA and total proctocolectomy. In each case, concern was voiced about misinterpretation of the proctocolectomy specimen as ulcerative colitis instead of Crohn's disease after the development of the Crohn's-like complications. Preoperatively, all eight patients had characteristic clinical, radiographic, and pathologic features of ulcerative colitis. Review of the pathology specimens indicated that all eight had ulcerative colitis. Crohn's-like complications are most likely related to chronic pouchitis, which probably is a form of recrudescent ulcerative colitis within the novel environment of the pouch. A diagnosis of Crohn's disease after IPAA surgery should only be made when reexamination of the original proctocolectomy specimen shows typical pathologic features of Crohn's disease, Crohn's disease arises in parts of the gastrointestinal tract distant from the pouch, pouch biopsies contain active enteritis with granulomas, or excised pouches show the characteristic features of Crohn's disease, including granulomas. There were no histologic differences in the total colectomy specimens between the eight ulcerative colitis study patients and 16 control ulcerative colitis patients who had a favorable clinical outcome after IPAA surgery groups. Crohn's-like complications and chronic pouchitis does not necessarily imply an incorrect original interpretation of ulcerative colitis by the pathologist.
OBSERVE: Occupancy-based system for efficient reduction of HVAC energy (2011)

Heating, cooling and ventilation accounts for 35% energy usage in the United States. Currently, most modern buildings still condition rooms assuming maximum occupancy rather than actual usage. As a result, rooms are often over-conditioned needlessly. Thus, in order to achieve efficient conditioning, we require knowledge of occupancy. This paper shows how real time occupancy data from a wireless sensor network can be used to create occupancy models which in turn can be integrated into building conditioning system for usage based demand control conditioning strategies. Using strategies based on sensor network occupancy model predictions, we show that it is possible to achieve 42% annual energy savings while still maintaining American Society of Heating, Refrigerating and Air-Conditioning (ASHRAE) comfort standards.
Large scale purification process for recombinant NS1-OspA as a candidate vaccine for Lyme disease. (1996)

A purification process was developed for the manufacture of NS1-OspA as a candidate vaccine for Lyme disease. NS1-OspA was expressed as a soluble recombinant protein in E. coli from 50 and 200 liter fermentations. A multistep bench scale procedure, including detergent treatment, sonication, Q-Sepharose chromatography, dialysis, and SP-Sepharose chromatography, was used to effectively purify NS1-OspA from E. coli to > 90% purity with a 35% yield. This procedure was subsequently modified and specific steps eliminated to create a manufacturing scale process for the purification of NS1-OspA. Continuous flow centrifugation, mechanical lysis, QA-52 anion exchange chromatography, acid induced precipitation, and cross flow filtration gave a final purity of > 75%, a recovery of > 70%, and measured endotoxin levels of < 5 micrograms/mg of protein. Unique features of this process include using unclarified lysates and a single use (disposable) resin for the batch chromatography step. This simple, cost effective production process provides a recombinant protein with the yield and purity suitable for use as a subunit veterinary vaccine.
Super-Resolution of Remotely Sensed Images With Variable-Pixel Linear Reconstruction (2007)

This paper describes the development and applications of a super-resolution method, known as Super-Resolution Variable-Pixel Linear Reconstruction. The algorithm works combining different lower resolution images in order to obtain, as a result, a higher resolution image. We show that it can make significant spatial resolution improvements to satellite images of the Earth's surface allowing recognition of objects with size approaching the limiting spatial resolution of the lower resolution images. The algorithm is based on the Variable-Pixel Linear Reconstruction algorithm developed by Fruchter and Hook, a well-known method in astronomy but never used for Earth remote sensing purposes. The algorithm preserves photometry, can weight input images according to the statistical significance of each pixel, and removes the effect of geometric distortion on both image shape and photometry. In this paper, we describe its development for remote sensing purposes, show the usefulness of the algorithm working with images as different to the astronomical images as the remote sensing ones, and show applications to: 1) a set of simulated multispectral images obtained from a real Quickbird image; and 2) a set of multispectral real Landsat Enhanced Thematic Mapper Plus (ETM+) images. These examples show that the algorithm provides a substantial improvement in limiting spatial resolution for both simulated and real data sets without significantly altering the multispectral content of the input low-resolution images, without amplifying the noise, and with very few artifacts
An object-oriented framework for the design of VLSI cells (2002)

The problem of enabling a VLSI designer to operate at various description levels during the chip development is addressed. In particular, the use of object-orientated programming has made it possible to solve the problem in a very simple and modular way. The EDIF format has been used for the input/output operations, and it is also possible to visualize cells and modify them. All these actions are available through the use of friendly windows with a suitable set of menus.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Wiener restoration of sampled image data: end-to-end analysis (1988)

Traditional formulations of the Wiener filter for image restoration have accounted for the blurring and noise that occur in (digital) image gathering, but they have failed to account for (1) the insufficient sampling that causes further degradations by aliasing and (2) the image-reconstruction degradations that ordinarily occur when the processed digital data are reproduced as a continuous representation. In this paper we formulate the Wiener filter as a function of the basic image-gathering and image-reconstruction constraints, thereby providing a method for minimizing the mean-squared error between the (continuous-input) radiance field and its restored (continuous-output) representation. Simulations demonstrate that this filter restores clearer and sharper images than the traditional filter. We also formulate the Wiener-characteristic filter to provide a method for explicitly specifying the characteristic, or feature, of the scene that one wishes to enhance or extract.
Zur Darstellung von Tetrahydropyran‐ und Tetrahydrofuran‐derivaten aus 1,7‐ bzw. 1,6‐Allyldiolen durch Dehydratation in der Allylstellung (1964)

Abstract A general method is described for the preparation of isoprenoid cyclic ethers by prototropic dehydration of the corresponding allyl‐l,7‐ or allyl‐l,6‐diols in the ally1 position. The formation of cyclic hydroxy ethers takes place from the corresponding epoxyallylalcohols by an analogous reaction.
Impact of gate stack on the stability of normally-Off AlGaN/GaN power switching HEMTs (2014)

We have examined the response of AlGaN/GaN power switching HEMTs to electrical bias stress. Three different gate stack structures were studied. In devices containing a ~ 5 nm thick AlGaN layer in the gate stack, both positive and negative shifts in the threshold voltage were observed following high blocking voltage stress, consistent with a short initial period of electron trapping followed by a longer period of de-trapping. Correlated changes in reverse bias leakage current were also observed, although this also occurred in devices containing only residual AlGaN in the gate stack. The data have been explained by a field-enhanced emission model in which an electron trapping to de-trapping transition occurs. The exact nature of the transition is found to be sensitive to a variety of parameters including trap energy, geometry, and initial and boundary conditions.
<title>Latching-type 2x2 and 1x4 fiber-optic switches</title> (2000)

The presented latching-type 2 by 2 and 1 by 4 fiber-optic switches are based on full wafer micromachining of silicon wafers using anisotropic wet etching in KOH. Bulk micromachining allows the low-cost batch fabrication of structures with very high precision suitable for fiber alignment. The optical fiber switches consist of two thermally driven silicon actuators, a coupled U-shaped cantilever via thin flexible silicon beams and a stiff platform prevents angular displacement of the fibers. Switches have been fabricated with high yield, high mechanical stability, and good optical properties. Using standard single- mode fibers, the switches exhibit a crosstalk of < - 60 dB. Insertion losses below 1 dB and about 1 dB are achievable for 1 by 4 and 2 by 2 switches, respectively. A power below 0.6 W and 1.0 W for the 2 by 2 and 1 by 4 micromechanical fiber switch is needed during the switching time. Bistable 1 by 2 optical fiber switches have been tested for more than 1 X 10<SUP>6</SUP> switching cycles without any failure and after more than one year at room conditions they do not show any degeneration of optical properties and switching behavior.
A new nitrogen-fixing species of pseudomonad: <i>Pseudomonas diazotrophicus</i> sp. nov. isolated from the root of wetland rice (1987)

A new rod-shaped, Gram-negative, polarly flagellated, and facultatively chemolithotrophic nitrogen-fixing bacterium isolated from the roots of rice (Oryza sativa) was described. The bacterium fixed nitrogen (N 2 ), used at least 55 organic compounds as sole carbon source, and did not require growth factors. It consisted of at least two distinct serogroups. The deoxyribonucleic acid base composition was 65.1–67.3 mol% G+C. The quinone system consisted of coenzyme Q 10 as a major ubiquinone and coenzyme Q 9 as a minor component. Cellular fatty acids consisted of 63–85% cw-9-octadecenoic acid, 7–10% octadecanoic acid, and 1–7% 3-hydroxytetradecanoic acid. These isolates are considered typical of a new species in the genus Pseudomonas and the proposed name is Pseudomonas diazotrophicus sp. nov.
Recognition Performance for Four Combinations of FM System and Hearing Aid Microphone Signals in Adverse Listening Conditions (1999)

These results suggest that a certain amount of flexibility is present when choosing an FM/HA combination. However, recognition performance via the HA microphones was consistently poorer than performance via FM transmission. Because relevant material also originates from fellow students (e.g., answering teacher-directed questions), input via the HAs is often as important as information originating from the teacher. The results suggest that attempts to improve performance for signals transmitted through the HA microphones in a classroom setting would benefit children with hearing loss.
T-Recs Table Recognition and Validation Approach (1999)

In this paper we resume the T-Recs block segmentation and layout analysis approach for tabular documents before we discuss an additional processing step for the proper recognition of potential tables. While the T-Recs results of the processing steps so far look pretty good on documents like articles which might occasionally contain the one or the other table (amongst regular paragraphs), the identification of tables gets confused by logical objects such as recipient address, date or company specific printing within business letters heads if those layout objects occur in a horizontal (left-of, right-o]) neighborship. To increase the precision z for correctly recognized tables in the above mentioned domain of business letters, we developed an additional processing step with has the purpose to determine clusters of cells that show up more evident features of a table than just the left-of, right-of relation between some blocks.
