Penerapan Metode Jala Sudut Proteksi Dan Bola Bergulir Pada Sistem Proteksi Petir Eksternal Yang Diaplikasikan Pada Gedung W Universitas Kristen Petra

Lightning protection system consist of external protection, grounding system and internal protection. Three methods to determine air termination are mesh size method, protective angle method and rolling sphere method. This paper describes the application of those methods on W building Petra Christian University. The result show that the building needs more lightning protection system based on rolling sphere method analysis

Interpretable Word Sense Representations via Definition Generation: The Case of Semantic Change Analysis

We propose using automatically generated natural language definitions of contextualised word usages as interpretable word and word sense representations. Given a collection of usage examples for a target word, and the corresponding data-driven usage clusters (i.e., word senses), a definition is generated for each usage with a specialised Flan-T5 language model, and the most prototypical definition in a usage cluster is chosen as the sense label. We demonstrate how the resulting sense labels can make existing approaches to semantic change analysis more interpretable, and how they can allow users — historical linguists, lexicographers, or social scientists — to explore and intuitively explain diachronic trajectories of word meaning. Semantic change analysis is only one of many possible applications of the ‘definitions as representations’ paradigm. Beyond being human-readable, contextualised definitions also outperform token or usage sentence embeddings in word-in-context semantic similarity judgements, making them a new promising type of lexical representation for NLP

No effect of short-term amino acid supplementation on variables related to skeletal muscle damage in 100 km ultra-runners - a randomized controlled trial

Background: The purpose of this study was to investigate the effect of short-term supplementation of amino acids before and during a 100 km ultra-marathon on variables of skeletal muscle damage and muscle soreness. We hypothesized that the supplementation of amino acids before and during an ultra-marathon would lead to a reduction in the variables of skeletal muscle damage, a decrease in muscle soreness and an improved performance. Methods: Twenty-eight experienced male ultra-runners were divided into two groups, one with amino acid supplementation and the other as a control group. The amino acid group was supplemented a total of 52.5 g of an amino acid concentrate before and during the 100 km ultra-marathon. Pre- and post-race, creatine kinase, urea and myoglobin were determined. At the same time, the athletes were asked for subjective feelings of muscle soreness. Results: Race time was not different between the groups when controlled for personal best time in a 100 km ultra-marathon. The increases in creatine kinase, urea and myoglobin were not different in both groups. Subjective feelings of skeletal muscle soreness were not different between the groups. Conclusions: We concluded that short-term supplementation of amino acids before and during a 100 km ultra-marathon had no effect on variables of skeletal muscle damage and muscle soreness

Beyond Perplexity: Examining Temporal Generalization in Large Language Models via Definition Generation

The advent of large language models (LLMs) has significantly improved performance across various Natural Language Processing tasks. However, the performance of LLMs has been shown to deteriorate over time, indicating a lack of temporal generalization. To date, performance deterioration of LLMs is primarily attributed to the factual changes in the real world over time. However, not only the facts of the world, but also the language we use to describe it constantly changes. Recent studies have indicated a relationship between performance deterioration and semantic change. This is typically measured using perplexity scores and relative performance on downstream tasks. Yet, perplexity and accuracy do not explain the effects of temporally shifted data on LLMs in practice. In this work, we propose to assess lexico-semantic temporal generalization of a language model by exploiting the task of contextualized word definition generation. This in-depth semantic assessment enables interpretable insights into the possible mistakes a model may perpetrate due to meaning shift, and can be used to complement more coarse-grained measures like perplexity scores. To assess how semantic change impacts performance, we design the task by differentiating between semantically stable, changing, and emerging target words, and experiment with T5-base, fine-tuned for contextualized definition generation. Our results indicate that (i) the model’s performance deteriorates for the task of contextualized word definition generation, (ii) the performance deteriorates more for semantically changing words compared to semantically stable words, (iii) the model exhibits significantly lower performance and potential bias for emerging words, and (iv) the performance does not correlate with cross-entropy or (pseudo)-perplexity scores. Overall, our results show that definition generation can be a promising task to assess a model’s capacity for temporal generalization with respect to semantic change

Abstract in Bahasa Indonesia : Sistem proteksi petir terdiri dari proteksi eksternal, sistem pembumian dan proteksi internal. Penentuan terminasi udara menggunakan tiga metode yaitu metode jala, sudut proteksi dan bola bergulir. Makalah ini menjelaskan tentang aplikasi ketiga metode tersebut pada gedung W UK Petra. Hasil yang diperoleh menunjukkan bahwa gedung W Universitas Kristen Petra membutuhkan tambahan sistem proteksi petir berdasarkan analisis dengan metode bola bergulir.
