Authors: Afsana Sharmin  , Kazi Md Hasanul Hoque  , Zhang Huapeng
Published: May 2022

Environment-friendly functional woven fabric with light weight has higher market demand in this era. This paper is aimed to prepare and characterize super-hydrophobic nylon-6 woven fabric by using silica nanoparticles, coupling agent 3-aminopropyltriethoxysilane (APTES), and a long chain hydrophobic agent hexadecyltrimethoxysilan (HDTMS). Synthesize of silica nanoparticles is processed with a modified Stöber method resulting in a mono-dispersed particle whose diameter is 51-60 nm. In this experiment chemical bonds presenting over the surface silica nanoparticle are Si–CH3 and Si–OH and Due to the reaction between the hydrolyzed APTES and the first layered surface, Si–OH group is specter onto the surface. The hydrolyzed HDTMS molecules created a bond to the surface by the formation of Si–O–Si bonds. As result, a long chain of organo-silane with low surface free energy is introduced onto the fabric surface. The hydrophobic coated surface appeared after spray coating with additional treatment without any adhesive. The super-hydrophobic nylon-6 woven fabric has been coated by spray method with static water contact angle 151.8. Characterization manifests a good self-cleaning tendency and low permeability difference.

This Project is to improve the compression ratio in particular in Diesel Engine and reduce heat rejection in cylinders. It is acquired by changing the material property by composition. Thermal barrier coatings have been applied to the internal combustion engine in the combustion chamber for simulating adiabatic changes. It is not only for reduction of heat rejection in-cylinder and thermal fatigue protection of underlying metallic surfaces, but it also for reduction of engine emissions and brake specific fuel consumption. Thermal Barrier Coatings (TBCs) in diesel engines lead to higher power density, fuel efficiency, and multifuel capacity due to higher combustion chamber temperature Using TBC can increase engine power. The application of TBC in the components is to enhance high temperature durability by reducing the heat transfer and lowering temperature of the underlying metal.

WCQMV : Design of A Wavelet Compression Based Quadratic Model for EEG Classification Using Multivariate Analysis
Authors: Ms. Shruti A. Chawale  , Dr. Swapnil B. Mohod  , Mr. Dinesh S. Chandak
Published: May 2022

Electroencephalogram (EEG) signals represent functioning of the brain, and assist in identification of multiple brain-related disorders including Epilepsy, Alzheimer’s disease, emotional states, Parkinson’s disease, strokes, etc. To design such models, a wide variety of machine learning & deep learning approaches are proposed by researchers. But these approaches use a black-box generic model for EEG classification, due to which their scalability is limited. To enhance this scalability, a novel feature augmented extraction model is proposed in this text. The model uses wavelet compression on input EEG data, and processes the compressed signal using a variance-based selection approach. Due to which, the model is capable of low-delay, and high accuracy classification for different brain-diseases. It evaluates wavelet-based features from input EEG data, and performs ensemble feature selection for improving feature variance. The wavelet features are able to convert input EEG data into different directional components, which assists in improving efficiency of feature representation & model training for different signal types. The proposed model uses a quadratic Neural Network (QNN) classification engine, and is capable of achieving an accuracy of 96.5% for different EEG classes. These classes include 3 types of Epilepsy, presence of Alzheimer’s disease, & evaluation of brain strokes. Due to use of feature variance-based classification, the proposed WCQMV model outperforms existing feature selection & classification models by 4% in terms of accuracy when averaged over multiple datasets. Moreover, the proposed model also improves speed of classification by 4.9% when compared with these models, thus making it useful for high-speed EEG processing applications. This performance improvement is possible due to effective feature reduction, which assists in identification of different EEG signal types. The model was tested on various EEG datasets including, IEEE Port Epileptic dataset, and BNCI dataset for Alzheimer & brain strokes. It was observed that the proposed model was capable of high-performance classification on each dataset, thereby indicating high-scalability across multiple EEG applications.

Gait Analysis for Surveillance
Authors: Prof. Sharon M  , B Joel Chris  , Deepak N  , Anish N  , Abdul Kareem
Published: May 2022

Gait refers to the patterns of movements the limbs make when walking. Human gaits refer to the variety of ways in which an individual can move, either naturally or as a result of training. The gait of each individual is as unique as their voice. On the basis of this knowledge, Machine Learning (ML) algorithms have been developed for gait recognition. Computer Vision (CV) techniques have facilitated the development of a wide range of approaches for identifying people by their movements in videos using both natural biometric characteristics (the human skeleton, silhouette, changes during walking) and abstractions. A gait recognition system identifies the human body based on its shape and the way it moves. A machine-learning system can recognize a person even if their face is hidden, turned away from the camera, or concealed behind a mask. An algorithm analyzes a person's silhouette, height, speed, and walking pattern to identify him or her. Gait recognition technology acquires data from multiple sources, such as video cameras and motion sensors. Data from these sources are then processed by a number of algorithms. Gait is recognized, data is processed, contours and silhouettes are detected, and individual features are segmented, according to the algorithm. After this, the feature extraction algorithm takes effect - this is what differentiates one gait from another. There are many different algorithmic requirements, and these algorithms can vary. Some algorithms, for example, are designed to process video information, while others employ sensor data. Because each gait is distinct, the identification algorithms are always confronted with new data. The system will assess future data better if it detects more gait variants. Assume the program compares two gaits that are highly similar. The algorithms for pattern recognition and silhouette segmentation have been trained to separate the tiny details and enter them into the database. This enables for more accurate gait categorization and improved results in the future.

Study of Operational Amplifier Test Procedure and Methods
Authors: Kumari Archana  , Pramendra Ranjan Singh
Published: May 2022

In this paper, we present about the study of operational amplifier test procedure and methods. Operational Amplifiers (Op-amps) are one of the most widely used building blocks for analog and mixed-signal systems. They are employed from dc bias applications to high-speed amplifiers and filters. General purpose op-amps can be used as buffers, summers, integrators, differentiators, comparators, negative impedance converters, and many other applications. The two-pole model widely used in the test analysis to assess the parameters of an op amp is not accurate and may be unsuitable for gain boosting op amp designs. A more complex model with more than two poles may require tedious analysis and a large amount of calculation. Most reported op amp measurement methods require a complicated test circuit, delicate calibration, and sophisticated test instrumentation. The practical bench test of the open loop gain along with other op amp characteristics are addressed alsoin this paper.

Contraddizioni e complessità del cohousing. Il contributo dell'abitare collaborativo alla generazione di spazio pubblico
Authors: Gresleri Jacopo
Published: May 2022

A partire dalla posizione di Dorit Fromm a proposito del cohousing, soluzione che parrebbe incoraggiare i residenti a socializzare costituendo al tempo stesso una potenziale strategia per il rinnovamento di piccoli quartieri, l'autore si interroga sul reale contributo "innovativo" di questa forma residenziale nel soddisfare le nuove esigenze di urbanità. Se, come dichiara Bianchetti, lo spazio pubblico contemporaneo è uno spazio che non è per tutti, che «non celebra la fissità ma l'occasione», sarebbe utile delinearne l'uso odierno e le sue specificità. Nella ricerca di risposte a questi interrogativi, analizzando la posizione degli Smithson a proposito del ruolo pubblico dell'intervento privato e rifacendosi ad alcuni esempi ereditati dalla città antica, l'autore identifica una possibile nuova forma di abitare collaborativo.

Diversi quartieri di edilizia residenziale pubblica, ma non solo, hanno subito svuotamenti e risignificazioni nell'organizzazione e uso degli spazi, mettendo in luce una ricerca paziente di nuove forme di gestione e uso del patrimonio pubblico. Molte sono le sperimentazioni e i tentativi che si sono dati, anche con forme di cooperazione pubblico/privato. Alcune iniziative e politiche promosse dai Comuni e dagli enti gestori hanno predisposto per esempio l'assegnazione temporanea in locazione a particolari categorie di popolazione, per garantire un uso continuativo del patrimonio ed evitare forme di degrado spaziale e sociale. Scopo del presente contributo è quello di provare a esplorare e restituire alcune di queste esperienze in atto, attraverso dei casi studio a Milano e Torino, indagandone le politiche alla base, le modalità di assegnazione degli alloggi e l'efficacia di alcuni esiti.
Un racconto lungo la domiziana. il valore del vivere informale
Authors: Simioli Maria
Published: May 2022

"Quali sono le ragioni che in poco più di trent'anni hanno portato a questo drastico cambiamento?" È a partire da questa domanda che l'autore tenta di ricostruire, in un volume che raccoglie le testimonianze di oltre cinquanta intervistati, la trama di una complessa vicenda che ha segnato, a partire dagli anni '80, il declino di un'intera area. Una narrazione che avviene su un doppio binario, in superficie il vivere informale dei tanti migranti giunti a Castel Volturno, e sullo sfondo la crisi economica, politica, sociale ed ambientale dove i fenomeni di abusivo costiero, la speculazione edilizia, la diffusa rete capillare della criminalità organizzata e il depauperamento delle risorse ambientali, non solo costituiscono la cornice entro cui queste vicende si disvelano ma rappresentano la radice del problema.
L'arroganza del progetto. Interrogazione sulle modalità minori di immaginare futuri
Authors: Moriconi Sofia
Published: May 2022

«Esiste un progetto minore? E se esiste, come è fatto?». Queste le domande al centro del volume di Camillo Boano figlio delle sue riflessioni nei primi mesi della pandemia. Un tempo in cui l'arroganza di un "fare progettuale" determinista e bio-tecno-scientista si è manifestata in tutta la sua violenza, ma anche in tutta la sua vacuità. L'autore del libro si chiede se è possibile praticare una minorità nelle discipline architettoniche ed urbanistiche, senza ritirarsi in altre discipline o contribuendo al disfacimento del progetto stesso. Grazie ad un ampia e disparata varietà di riferimenti, Boano suggerisce di mettere al centro l'incessante divenire del processo generativo piuttosto che il prodotto finale. Derivandole dai lavori di Agamben, Esposito e Mignolo, propone tre declinazioni della minorità: inoperativa, istituente e decoloniale. Questa riflessione si interroga sulla natura del processo generativo suggerito e sull'ampiezza dei margini di un "soggetto progettante".
Politiche di sviluppo ambientale tra fiscalità e green economy
Authors: Mendola Daniela
Published: May 2022

Ormai diffusa è l'immagine di un turista "responsabile" che approccia al consumo con un atteggiamento critico, perché più attento alla ecosostenibilità dei territori e orientato a scegliere mete che abbiano attuato una politica di conservazione ambientale. Al turista responsabile fa da pendant un turismo green che impone alle imprese di adottare comportamenti in linea con uno sviluppo sostenibile. Le misure di "fiscalità verde" appaiono parte essenziale delle politiche ambientali e fiscali, orientando comportamenti individuali e collettivi e soprattutto responsabilizzando imprese, consumatori e istituzioni. L'attuale sistema ordinamentale è orientato ad una politica di "promozione" che individua accanto al fine primario del prelievo, qual è appunto il concorso al sostentamento delle spese pubbliche (art. 53 Cost.), dei fini c.d. "accessori" anche di carattere fiscale che valorizzino la funzione impositiva in funzione del soddisfacimento dei diritti fondamentali. Lo strumento fiscale, dunque, viene utilizzato al fine di incentivare comportamenti ecosostenibili da parte degli operatori commerciali, sia imponendo specifici tributi correlati a condotte inquinanti (c.d. "tributi ambientali"), sia riconoscendo agevolazioni fiscali a fronte di comportamenti virtuosi.
Il ritorno del Ministero del Turismo: il nuovo capitolo di una saga decennale
Authors: Sale Veronica
Published: May 2022

Nel 2021, a quasi trent'anni dalla sua abolizione, il Ministero del Turismo fa il suo ritorno nell'architettura del Governo italiano come strumento strategi-co contro la crisi economica causata dalla pandemia di Covid-19. Nonostan-te i numerosi elogi da parte degli operatori del settore turistico, la riforma potrebbe sollevare dubbi tra coloro che hanno sempre criticamente eviden-ziato la tendenza dello Stato a intervenire in una materia di competenza esclusiva delle Regioni.
Wedding package e danno da "vacanza rovinata"
Authors: Orti Francesca
Published: May 2022

Il Tribunale di Firenze ha respinto, per mancanza di prova, la domanda di risarcimento del danno da "vacanza rovinata" proposta da una coppia che, dopo aver acquistato un pacchetto turistico comprendente la celebrazione del matrimonio su una spiaggia delle Hawaii, aveva lamentato alcune carenze, quali: la vista della camera sul campo da Golf invece che sull'Oceano, come previsto nel catalogo, la celebrazione della cerimonia su una spiaggia diversa da quella pattuita; il mancato riconoscimento del matrimonio in Italia per as-senza della convalida dell'Apostille. L'A., delineato il quadro normativo e richiamati i precedenti giurisprudenziali in tema di "danno da vacanza rovinata" in relazione ai viaggi di nozze, ha rimarcato il dovere d'informazione dell'operatore turistico nell'asimmetria informativa col turista/consumatore, anche con riferimento ai profili di pubblicità ingannevole per mancato riscontro con il catalogo informativo
What merit order for hydrogen development? Prospective observations from the French context
Authors: Appert Olivier , Geoffron Patrice
Published: May 2022

This article is devoted to an analysis of the prospects for the development of hydrogen uses, from a decarbonisation perspective. Based on a comparison of low-carbon hydrogen production technologies (from renewables, nuclear, CCS) and their prospective costs, a «merit order» in the uses is determined, leading to prioritise substitution in heavy industry first, then in heavy transport. We also draw attention to the safety of hydrogen uses, whose explosiveness calls for the greatest vigilance, at the risk, otherwise, of hindering the deployment of hydrogen uses
A perspective of global biofuel policies
Authors: Das Sudip
Published: May 2022

Biofuels have drawn the attention of policymakers as a medium to address concerns of energy security, climate change and socio-economic development. The paper examines the biofuel policies of the major biofuel producing nations and analyzes the key instruments being adopted by them during the last decade such as blending mandates, financial incentives, subsidies, import tariffs, greenhouse gas (GHG) emission and carbon trading. The countries are categorized by continent and covers Asia (India, China, Malaysia, Indonesia and Thailand), Europe (European Union, Germany and France), South America (Brazil, Argentina), North America (USA, Canada) and Australia. The paper assesses whether the blending mandates had the desired impact on realization of policy targets and examines the impact of biofuel policies on the socio-economic development and environmental sustainability in these nations. Most countries continue to use sugarcane, corn, grains, and vegetable oils as feedstock for biofuel production thereby raising concerns about their adverse impact on food prices and food availability to the underprivileged people. Biofuel policies for this paper refer to policy instruments, strategies and programs which were established to aid and manage the production and consumption of biofuels - both ethanol and biodiesel.
Does institutional quality affect electricity supply? A panel SUR estimation
Authors: Venter Alanda , Inglesi-Lotz Roula
Published: May 2022

Electricity availability and generation have a significant impact on the economies internationally. Understanding the factors affecting the electricity supply sector is imperative towards improving the industry and achieving a sustainable energy future for all as per the United Nations Sustainable Development Goals (SDGs) to 2030. This study mainly focuses on the institutional quality factors that impact the electricity supply of twenty countries, representing various electricity market structures and supply mixes, to derive holistic policy suggestions. Institutional quality will be defined as property rights, corruption perception, voice and accountability, government efficiency, the rule of law and regulatory quality in the study. To do so, a Seemingly Unrelated Regression model will be used for the period 2003 to 2018. The results indicate that improved institutional quality stabilises markets, affecting the electricity supply.
