Abstract We have demonstrated the degradation of perovskite solar cells (PSCs) due to transformation pinholes into current leakage points. intentionally formed in (PVK) layer using laser processing techniques evaluate impact on performances PSCs and observe behavior pinholes. The initial performance cell (PSC) with indicates that all did not work as points immediately after fabrication. However, 2 weeks storage a dark desiccator at room temperature 3 minutes activation by Air Mass 1.5 Global...

Abstract Perovskite solar cells (PSCs) have attracted much attention due to their high-power conversion efficiency and solution processability. Establishing a method easily evaluate the defects present in PSCs is key factor achieving efficient large area PSCs. In this work, we established simple identify by combining several imaging methods. We revealed that scratches can be identified electroluminescence, photoluminescence, thermal believe proposed methodology will provide important...

During the massive Tohoku earthquake, while landlines and mobile phone lines got stuck, Twitter were used to exchange information about evacuation. On 11 March, number of tweets from Japan dramatically increased 33 million, 1.8 times higher than average figure. However, since texts on are unstructured data, more complex other text media, it is difficult find a suitable evacuation center. Not only in Twitter, people but also need combine such as map information, shop Since takes much time do...

Lifestyle-related diseases can be reduced by making daily dietary choices. Functional components in foods have the potential to provide benefits this regard. We constructed a knowledge graph that connects functional of recipes, and developed recommendation system suggest dishes may help alleviate lifestyle-related diseases. As requirements vary widely depending on specific individual conditions, these are combined form vast probability distribution. Our proposed uses probabilistic logic...

We have studied the reliability of low-temperature polycrystalline-silicon thin-film-transistors (TFTs) under dynamic bias stress using a CMOS inverter circuit. A remarkable decrease in mobility and ON-current was observed n-channel TFTs stress. The degradation depends strongly on falling edge voltage pulse number pulses. Observation by emission microscopy revealed that hot electrons were generated around drain region TFT. also confirmed with lightly doped less degraded. Based these...

Interoperability between different systems is becoming a more important issue as computer networks expand. In this paper, we propose Bee-gent (Bonding and Encapsulation Enhancement Agent), distributed system development-framework that aims to provide coordination RDBMSs, legacy systems, software packages, so forth. The mechanism an integration of interaction protocols explicitly describe the relationship elements system. Our approach split into flow for overall problem solving sequence...

With the recent fast expansion of networks, interconnection heterogeneous systems via networks is drawing increasing attention. In this context, authors propose Bee-gent (Bonding and Encapsulation Enhancement aGENT) agent framework, whose objective to allow flexible between legacy systems, databases, other existing by providing coordination communication functions for distributed system components. proposed network, interaction protocols describing interactions components are divided global...

UDDI is a standard registry for Web services, but so far its search functionality has been limited to keyword search. These authors propose enhancement called Matchmaker, which supports semantic service capability discovery. Since September 2003, they have deployed Matchmaker in one of four official registries operated by NTT-Communications. In this article, introduce and illustrate client tools that lower the threshold using semantics Experiments show consumes about 5 seconds more time than...

The goal of this paper is to describe a method automatically extract all basic attributes namely actor, action, object, time and location which belong an activity from Japanese weblogs. Sentences retrieved weblogs are often diversified, complex, syntactically wrong, have emoticons new words. There some works that tried users’ activities in sentences web However, these several limitations, such as inability extracting infrequent activities, high setup cost, limitation on the types can be...

The existing music recommendation systems rely on user's contexts or content analysis to satisfy the users' playing needs. They achieved a certain degree of success and inspired future researches get more progress. However, cold start problem limitation similar have been pointed out. Therefore, this paper proposes unique method using 'renso' alignment among Linked Data, aiming realize agent in smartphone. We first collect data from Last.fm, Yahoo! Local, Twitter LyricWiki, create large scale...

This paper proposes a method of identifying and aggregating literal nodes that have the same meaning in Linked Open Data (LOD) order to facilitate cross-domain search.LOD has graph structure which most are represented by Uniform Resource Identifiers (URIs), thus LOD sets connected searched through different domains.However, 5% values (strings without URI) even de facto hub LOD, DBpedia.In SPARQL Protocol RDF Query Language (SPARQL) queries, we need rely on regular expression match trace...

High mobility bottom-gate poly-Si thin film transistors (TFTs) have been successfully fabricated on a hard glass substrate using XeCl excimer laser annealing and ion doping techniques. The authors used an a-Si:H which is deposited by plasma-enhanced chemical vapor deposition (PECVD) as precursor film, then they crystallized the a-Si annealing. maximum field effect grain size obtained were 200 cm/sup 2//V-s (n-channel), 250 nm, respectively. TFTs showed excellent transfer characteristics,...
