Because of its unique decentralization, encryption, reliability, and tamper-proof, the block chain system makes smart contracts break through the shackles of the lack of trusted environment, and its application field keeps expanding. We read the source code and official documents of Bitcoin, Ethereum, and Hyperledger to explore the operation principle and implementation mode of smart contract. By analyzing the evolution process of smart contracts in blockchain and the sequence of its function expansion, according to the multirole business process of supply chain, we design a semipublic smart contract chain model based on Ethereum and Hyperledger in order to provide useful inspiration and help for the future research of smart contracts in blockchain applied in supply chain.

Researchers all over the world are aiming to make robots with accurate and stable human-like grasp capabilities, which will expand the application field of robots, and development of a reasonable grasping strategy is the premise of this function. In this paper, the improved deeplabV3+ semantic segmentation algorithm is used to predict a triangle grasp strategy. The improved model was trained on the relabeled Cornell grasp datasets and tested on self-collected datasets. Compared with the existing rectangular grasp strategy, the proposed algorithm and triangle grasp strategy have achieved outstanding performance in stability, accuracy, and speed. Finally, based on the ROS platform, this paper deploys the trained model and verifies the real effect of the trained grasping strategy prediction model, and achieves excellent grasping effect.

يدخل هذا البحث ضمن مجال الدراسات اللغوية، وتحديدًا النحوية والدلالية. إذ اختص بدراسة الجملة الاسمية والفعلية ودلالتها في سورة (المؤمنون)، واستنباط دلالات هذه التراكيب، واعتمدت فيه منهج الاستقراء التحليلي: إذ يستقري الباحث تراكيب الجملة الاسمية والفعلية في سورة المؤمنون، ثم يعمد إلى تحليلها وبيان دلالتها المعنوية . يهدف هذا البحث إلى تسليط الضوء على القيم الدلالية الكامنة في الجملة الاسمية والفعلية في بناء التركيب النحوي، ومحاولة استجلاء المعاني الدلالية المختلفة في الجملة الاسمية والفعلية في حقل التطبيق من القرآن الكريم . إنّ دراسة التركيب النحوي واستقراء دلالته في القرآن الكريم أنجع وسيلة لفهم كلام الله – سبحانه وتعالى- أتمّ فهم، إذ تتكشف أمام الباحث لطائف لغوية ومعنوية عند الوقوف على كلّ تركيب . ودراسة تراكيب الجملة الاسمية والفعلية في سورة واحدة من سور القرآن تعمّق إدراك القارئ لبديع النظم القرآني، فيلاحظ اختلاف التراكيب ظاهرًا، واتّفاقها في الدلالة باطنًا، وذلك يعزّز المعنى المنشود من مجيء هذا النظم خاصة . الكلمات الدالة: التركيب النحوي، الجملة الاسمية والجملة الفعلية، دلالة الجملة الاسمية والفعلية. Abstract This is one of researches which comes within the field of linguistic studies, specifically grammatical and semantic. The research is specialized in the study of the semantic values inherent in the grammatical structure of some nominal and adverbial sentences, and devising the meanings of these semantic structures, I adopted the method of analytical induction. The researcher extrapolates the grammatical structures in some nominal and adverbial sentences in Surat Al-Muminun, and then proceed to analyze them، and statement its linguistic indication. The aim of this research is to shed light on the semantic values inherent in the grammatical structure of some nominal and adverbial sentences, and a trial to elucidate the different semantic meanings of different linguistic methods in the application field of the Holy Quran. The study of the grammatical structure and the extrapolation of its indication in the Holy Quran is the most effective method to understand the words of God – Glory be to him – the best understanding, As the researcher unfolds before the linguistic and moral groups when standing on each structure. The study of the grammatical structures in some nominal and adverbial sentences in one Surah of the Qur'an, deepening the reader's awareness of the Exquisite pronunciation of the Qur'anic composing, it is noted the different structures virtually and their agreed in indication inwardly. This reinforces the desired meaning from coming jurisdiction of these exquisite words without another. Kew words: grammatical structures, nominal and adverbial sentences, semantic values.

Artificial intelligence increasingly attracts attention and investments. However, appropriating value from this general-purpose technology (GPT) can be difficult. To understand these challenges, this article analyzes why IBM failed to generate significant profits from IBM Watson Health despite its promising starting points. The findings suggest that, considering the characteristics of GPT, an overly closed approach for taking it to market contributed to the failure. Furthermore, conditions such as the immaturity and the complexity of the application field intensified the challenges. This study suggests that using a strong appropriability regime in open innovation can enhance the appropriation of value from a GPT.

Surplus lignin, which is inefficiently used, is generated in the forestry industry. Currently, most studies use lignin instead of phenol to synthesize thermosetting resins which cannot be reprocessed, thus affecting its application field. Thermoplastic phenolic resin has an orderly structure and excellent molding performance, which can greatly improve its application field and economic value. Herein, phenol was partially replaced with enzymolysis lignin (without treatment), generating lignin-based high-ortho thermoplastic phenolic resins (LPRs), and then lignin-based phenolic fibers (LPFs) were prepared by melt spinning. FTIR, 13C-NMR and GPC were used to characterize the ortho–para position ratio (O/P value), molecular weight and its distribution (PDI), and rheological properties of the resin. TG, XRD, SEM and tensile property studies were used to determine the thermal stability, orientation, and surface morphology of the fiber. Lignin addition resulted in the decline of the O/P value and molecular weight of the resin. For the 10% LPR, the O/P value, Mw, and PDI were 1.28, 4263, and 2.74, respectively, with the fiber exhibiting relatively good spinnability. The tensile strength and elongation at break of the 10% LPF were 160.9 MPa and 1.9%, respectively. The addition of lignin effectively improved the thermal properties of the fiber, and the carbon yields of 20% LPF before and after curing were 39.7% and 53.6%, respectively, which were 22.2% and 13.7% higher than that of the unmodified fiber, respectively.

Low-power machines were commonly considered as the main application field of concentrated windings. However, a lot of paper have recently been published, which address both the theory of these windings and specific cases of their application for large synchronous machines. The article presents an analysis of the parameters of concentrated windings having various configurations intended for use in high-power gear and gearless wind generators. In assessing the winding, not only the high winding factor value was taken into account, but also the star of slot EMFs, harmonic spectra of the MMFs and EMFs, the cogging torque component and torque pulsation under load, as well as emerging losses. It is shown that the well-known advantages of concentrated windings over distributed windings can be fully realized by choosing the appropriated numbers of slots and poles.
