BackgroundPancreatic fistula (PF) remains the most serious complication after digestive surgery. It is difficult to prevent because of the inability to visualize the leakage of pancreatic juice during surgery or to evaluate the protease activity of leaked fluid, which is responsible for PF formation.
MethodsThe fluorescence intensities of a chymotrypsin probe (glutamyl‐phenylalanine hydroxymethyl rhodamine green with added trypsin) in pancreatic juice and in intestinal or abdominal fluids drained after pancreatic resection were evaluated. The chymotrypsin probe was sprayed on to filter papers that had been placed on the resected pancreatic stump in patients undergoing pancreaticoduodenectomy or central pancreatectomy. The ability of this technique to visualize the leakage of pancreatic juice and predict postoperative PF formation was assessed....
Most architecture of mobile ad hoc network is in the form of decentralized, self-configuring and dynamic topologies. Nodes are mobile in network. The mobility of node in network is common problem in peer-to-peer technology. Object replication is one of the techniques applied in order to share objects in the mobile peer-to-peer environment. Predicting the estimated time for the node to exit is a great...
Access to essential drugs is a key element for sustaining good health but medicines have become inaccessible to many because of very high prices. Consumers have no access to information regarding cheaper drugs that are alternatives to more expensive proprietary drugs. This study aimed to promote access to such information through the use of Short Message Service (SMS) and improve price transparency...
A TCP session uses IP addresses (+ IP port) of both end points as identifiers. Therefore when a mobile handover to a new AP that belong to a different subnet/domain, the IP address will changes and ongoing TCP connections are reset. Several approaches have been proposed to solve this problem, and one of which was to modified the TCP/IP stack to update the changes of the IP address for the ongoing...
Many PC keyboard layouts have been developed for Myanmar language (Burmese), but there is no standard keyboard layout yet. This paper reports a comparison of well-known Myanmar keyboard layouts such as CE, Win Myanmar, Zawgyi Myanmar, MyaZedi, and Myanmar3. The primary research focuses on examination of keyboard mapping, keystrokes per character (KSPC) and characters per minute (CPM). Its result shows...
To preserve ongoing connections and minimize the packet loss when the mobile node (MN) performs a handover, we introduce the low loss mobility agent (LLMA) in to the SIP systems. This agent works as an intermediate B2BUA between the MN and CN to minimize the loss packet when MN experiences a handover. In this paper, we will provide details working procedure to support the UDP session, and brief discussion...
This paper presents a tool, which is implemented on the MATLAB/Simulink environment realizing a user friendly GUI system with object oriented configuration, to analyze the dynamical behavior of industrial electrical power system with a customerpsilas gas turbine power plant. A model consisting of a gas turbine system including the steam flow, a synchronous generator with mechanical and electrical...
Grid computing has been widely spread in pragmatic areas and scientific research areas in order to achieve more powerful computation than ordinary computation by single computer. Globus Toolkit4 (GT4), which has been the de facto standard middleware in Grid, gives to us many chances of submitting jobs, especially using WSRF technologies. However, in case of cluster type grid using GT4, rules for job...
We introduce a first ever soft keyboard for stylus-based devices such as personal digital assistant (PDA) for Khmer, official language of Cambodia. The contribution of this study is twofold - a key layout arrangement and a word-based predictive text entry method. First, we design a non-QWERTY key layout in which consonants and vowels are grouped phonetically and orthographically, respectively. As...
In the next generation network (NGN), various kinds of advanced smart mobile terminals will be used for various communication services. We believe that text typing on small mobile devices will become more popular than it is today and also necessary for developing countries such as Myanmar (Burma), Cambodia and Bangladesh etc. In these countries, however, there is no proper or easy text input method...
In this paper we describe a framework to automatically customize an ongoing communication service whenever a terminal discovers a new link (either wireless or wire-line), which can be used for communication as a secondary link to the Internet. This framework makes use of the information that the server can obtain, as well as the ability to communicate using two links simultaneously at the terminal...
The interface of mobile phone in Bangladesh is mostly in English. Few mobile operators introduced Short Messaging Services in Bangla. Text entry in Bangla in mobile phone is not simple due to the structure and large number of characters in this script. The objective of this paper is to propose an easy and faster mobile input method. We proposed frequency based two-layer multitap (FBTLM) Bangla input...
In this paper, we consider the control of a system with time-delay and constraints on states and control inputs. It is well-known that the the presence of time-delay and physical constraints in dynamical systems causes the instability and preference degradation. In designing control laws for the system, we apply the following approach. We design a predictive controller and stabilize the system with...
In recent years, Web service technologies are becoming more and more important communication scheme for grid environment. WSRF-based resource management components, such as WS-GRAM in GT4, lay emphasis on how to make existing procedures such as local scheduler be invoked via HTTP, so that they inevitably have two problems described below. (1) If assumed environment is cluster type grid, each worker...
In this paper, we present the architecture of efficient resource mapping between global resources and local resources for grid environment. Many current grid infrastructures which adopt WSRF as a communication scheme lay emphasis on only managing resource information from local scheduler. As a result, they don't define how each local node should manipulate a specific submitted job using the resource...
In robot teleoperation there is a mounted camera on a robot and the operation is usually performed from a remote site using captured images by the mounted camera. Even though color cameras provide many useful information of a remote site, robot teleoperation using color cameras are highly effected by environmental conditions such as lighting, colors, smoke, etc. and there might be a case that cameras...
This paper presented a report about a multimedia project carried out in underdeveloped area in Indonesia. We first explained assumptions of the project, then followed by discussion on network design issues using wireless LAN and power line communication (PLC) based the assumptions. The network design then would be a platform for the e-learning applications we created based on feedback from local people,...
Periodical information collection from unreachable remote terrain and then transmit information to a remote base station is one of the targeted applications of sensor networks. But the energy restriction of battery operated sensor nodes certainly makes this task difficult and complicated because once deployed in the target field, it is not feasible to change the battery periodically. Therefore, in...
