Checkbox components take on a different shape when they are in a Checkbox- Group . If the checkbox was originally not in a CheckboxGroup , the shape of the checkbox does not change automatically when you put it in one with setCheckboxGroup() . (This also holds when you remove a Checkbox from a CheckboxGroup and make it independent or vice versa.) In order for the Checkbox to look right once added to group , you need to destroy and create ( removeNotify() and addNotify() , respectively) the Checkbox peer to correct the shape. Also, it is possible to get multiple true Checkbox components in group this way, since the new CheckboxGroup ’s current selection does not get adjusted. To avoid this problem, make sure it is grouped properly the first time, or be sure to clear the selections with a call to getCheckbox- Group().setCurrent(null) .
facilitation of learning with a range of digital technologies. Integration of technology encourages and provides opportunities for learners to think critically and creatively. Thus, language teaching is also employing initiatives to be part of the technological advancement especially in teaching ESL. In line to that, emergence of various digital tools requires educators to identify the suitability and acceptance among the learners to ensure the effectiveness of the integration. Therefore, this study aims to investigate the students’s acceptance of using Piclits as a digital tool to help them enhance their writing skill. Hence, this study employed a survey design distributed to 32 Year 4 pupils in a primary school in Selangor. Data were gathered using a questionnaire containing 10 items to obtain perceptions from the respondents on the usage of Piclits. The collected data were then analysed and reported using frequencies and percentages. The analysis of the questionnaire survey reflected most of the pupils having a positive feedback on integrating Piclits in their writing activity. The findings would be beneficial to ESL language teachers as it could be an added resource to assist them in teaching the writing skill and encourage pupil’s interest towards getting them to write. However, it is suggested that teachers may also look into error correction feedback while using this tool as a means of enhancing writing skills among students.
A BSTRACT : Mankind has always strived to give life like qualities to its artifacts in an attempt to find substitutes for himself to carry out his orders and also to work in a hostile environment. The popular concept of a mechanical arm is of a machine that looks and works like a human arm. The industry is moving from current state of automation to Robotization, to increase productivity and to deliver uniform quality. The industrial robots of today may not look the least bit like a human being although all the research is directed to provide more and more anthropomorphic and human like features and super-human capabilities in these. One type of robot commonly used in industry is a robotic manipulator or simply a mechanical arm. It is an open or closed kinematic chain of rigid links interconnected by movable joints. The system provides a pick and place robotic arm which is a soft catching gripper system. It can be used to pick and place objects as needed. This arm is mounted on a robotic vehicle that can be controlled wirelessly through an android mobile phone. The android phone acts as the controller used to transmit the control commands through Bluetooth. These commands are used to operate the robot front, backwards, left and right directions. The android phone is used as remote controlling device used to control the robotic vehicle. The use of Bluetooth technology provides adequate operational range with instant transmissions. The microcontroller after receiving these commands, operate required motors through the driver IC. It can be remotely controlled by any android device. This machine may be used in industrial or even domestic purposes and even as a help for industrial workers.
ABSTRACT : The popular concept of a robot is of a machine that looks and works like a human being. The industry is moving from current state of automation to Robotization, to increase productivity and to deliver uniform quality. The industrial robots of today may not look the least bit like a human being although all the research is directed to provide more and more anthropomorphic and humanlike features and super-human capabilities in these. One type of robot commonly used in industry is a robotic manipulator or simply a robotic arm. It is an open or closed kinematic chain of rigid links interconnected by movable joints. In some configurations, links can be considered to correspond to human anatomy as waist, upper arm and forearm with joint at shoulder and elbow. At end of arm a wrist joint connects an end effect which may be a tool and its fixture or a gripper or any other device to work.
Nowadays, development of technologies especially in robotic are widely grown up. A variety design of robots has been develop in recent years in order to improve the design and their performance. A robot is a virtual or mechanical artificial agent. It is usually an electro-mechanical system which, by its appearances or movements, conveys a sense that it has intent or agency of its own. Today, commercial and industrial robots are in widespread use performing jobs more cheaply or with greater accuracy and reliability than humans. They are also employed for jobs which are too dirty, dangerous or dull to be suitable for humans. Typical applications of robots include welding, painting, ironing, assembly, pick and place, packaging and palletizing, product inspection and testing, all accomplished with high endurance, speed, and precision (Gunderson and Gunderson, 2009)
R c ) whose respective coordinates correspond to the critical values of P and R at which the plateau is attained. Through observations made on many different systems it has been found that the approach to the plateau sometimes exhibits "ideal" behavior in that the pick-up isotherm is almost linear. An example is the pick-up of triethylamine with polyethylene-coated magnetic particles that demonstrates an almost linear relationship between the P and R parameters up to the plateau (Ngeh 2002). On the other hand, the isotherm for the pick-up of bromobenzene with the same type of particles demonstrates a significant departure from linearity and, as such, can be classified as an example of a “non-ideal” system (Ngeh 2002). Other variations in the behavior of the isotherm have been observed such as the high rate of approach to the plateau exhibited in the case of the pick-up of iodobenzene by polyethylene-coated magnetic particles (Ngeh 2002).
In this way, the requirement for the disclosure and the determination of exercises happening inside and crosswise over recordings for gathering data most pertinent to the given assignment has cultivated the field of multi- stream abridge. At the heart of multi-stream summarization there is a "pick and leave" issue that minute to minute a perfect or ideal spectator must unravel: pick the most enlightening stream; identify, assuming any, intriguing exercises happening inside the present stream; leave the took care of stream for the following "best" stream. In this paper, we give an alternate point of view to such "pick and leave" issue in light of a principled structure that binds together clear visual consideration conduct and ideal rummaging.
ABSTRACT Recent work demonstrated that the Niemann-Pick C1 (NPC1) protein is an essential entry receptor for filoviruses. While previous studies focused on filovirus entry requirements of NPC1 in vitro, its roles in filovirus replication and pathogene- sis in vivo remain unclear. Here, we evaluated the importance of NPC1, and its partner in cholesterol transport, NPC2, by using a mouse model of Ebolavirus (EBOV) disease. We found that, whereas wild-type mice had high viral loads and succumbed to EBOV infection, Npc1 ⴚ/ⴚ mice were entirely free of viral replication and completely protected from EBOV disease. Interestingly, Npc1 ⴙ/ⴚ mice transiently developed high levels of viremia, but were nevertheless substantially protected from EBOV challenge. We also found Npc2 ⴚ/ⴚ mice to be fully susceptible to EBOV infection, while Npc1 ⴚ/ⴚ mice treated to deplete stored lysosomal cholesterol remained completely resistant to EBOV infection. These results provide mechanistic evidence that NPC1 is directly required for EBOV infection in vivo, with little or no role for NPC1/NPC2-dependent cholesterol transport. Finally, we assessed the in vivo antiviral efficacies of three compounds known to inhibit NPC1 function or NPC1-glycoprotein binding in vitro. Two compounds reduced viral titers in vivo and provided a modest, albeit not statistically significant, degree of protection. Taken together, our results show that NPC1 is critical for replication and pathogenesis in animals and is a bona fide target for develop- ment of antifilovirus therapeutics. Additionally, our findings with Npc1 ⴙ/ⴚ mice raise the possibility that individuals heterozy- gous for NPC1 may have a survival advantage in the face of EBOV infection.
iest ion beam delivered by the PIAVE-ALPI accelerator complex and detecting both projectile-like and target- like ions. To this end the large solid angle magnetic spectrometer PRISMA was coupled to a second arm for the detection of the heavy fragments in kinematic coincidence with the light ones selected and identified with the spectrometer. The data analysis is still in progress and will allow to compare the yields of both light and heavy partner with theoretical predictions performed with the GRAZING code to get quantitative information on transfer channels and the effect of evaporation and fission on the production rate of primary fragments. The mass integrated Z distribution, extracted from the experimental data, evidenced the population of proton pick- up channels that, in conjunction with the neutron stripping ones from the 130 Te, open the path for the production
MEMS sensor is a Micro-Electromechanical System. It is a sensor which is used to detect the motion of operator’s hand. In this project, there are two MEMS sensors are in used. One for detecting the motion for Forward, Backward, Left and Right direction whereas other is used for detecting the motion for pick up and pick down movement of robotic arm.The Flex Sensor patented technology is based on resistive carbon elements. As a variable printed resistor, the Flex Sensor achieves great form-factor on a thin flexible substrate. When the substrate is bent, the sensor produces a resistance output correlated to the bend radius—the smaller the radius, the higher the resistance value.
We begin by translating the classical Nevanlinna Pick interpolation problem as given in Section I into the language of behavioral systems theory and address some issues that arise out of such a formulation. We will only consider the scalar interpolation problem in this paper, and hence we consider C ∞ -behaviors B with two manifest variables (u, y) that take values in R 2 . A behavioral formulation of Nevanlinna-Pick interpolation has been done in , where a characterization of solutions of a “Subspace Nevanlinna Interpolation Problem” was obtained in terms of kernel rep- resentations. In this paper we show obtain a characterization of all solutions in terms of image representations. Such a characterization has an advantage over : controllability of all solutions obtained as image representations is guaranteed, unlike in a characterization in terms of kernel representations. Consider a controllable behavior B given by an observable image representation:
Many uncertainties thus remain regarding the precise and complete functions of the NPC1 and NPC2 proteins. It has also been suggested that they could be involved in fusion/fission events between the late endosome and the lysosome. One important (and yet unanswered) question is whether these proteins - at least NPC1 - also directly regulate or mediate retrograde transport of other lyso- somal cargo. Glycolipids, which constitute the main lipid accumulation in the brain, by opposition to the quantita- tively minor cholesterol imbalance in neurons, are good candidates. The storage of GM2 and GM3 gangliosides in brain is not specific. Yet, the increase of GM2 occurs much earlier and is more prominent in NP-C than in other lysosomal diseases . But no data supportive of a glycolipid transport by NPC1 or NPC2 have been pub- lished so far. It has also been postulated that sphingosine storage could be the primary trigger of a pathogenic cas- cade in NP-C since this lipid can disrupt calcium homeo- stasis in NPC1 lysosomes [85,86]. The latter studies, however, were conducted in non neural NP-C cells or in a drug (U18666A)-induced model. In brain, currently avail- able data show a close link between accumulation of the different lipids, both in developmental terms and after therapeutic attempts [63,64]. No ganglioside or sphin- gosine accumulation can be detected in the brain of human fetuses at 24 gestational weeks, although the liver already shows a pronounced storage. Arguments for and against each of the accumulated lipids as the offending metabolite have recently been discussed . Most likely, stored lipids (and possibly other metabolites) collectively contribute to the pathology. More work is clearly needed to better understand the cause of brain dysfunction in Niemann-Pick C disease. In particular, the mechanisms by which Purkinje cells and other neurons degenerate remain unclear.
I appreciated the lack of voice-over; it would have been superfluous and perhaps distracting. This ad may not necessarily motivate people to pick up the phone—there’s no “ask” at the end—but it made for effective branding. The robotic welding arms are a cool touch, and the tagline—“Because life feels richer when you feel secure”—rang true. It’s better to feel rich than to be rich, right? There are fewer tax and estate problems.
