Deep Learning (DL) has contributed a lot in the field of industrial maintenance, in particular predictive maintenance by detecting potential failures and breakdowns before their appearance. Unfortunately, the DL has some limitations like the need for a large amount of data to produce an effective prediction model and also the fragility of the model in the face of changes in operating conditions. Another approach, the Transfer Learning (TL), had demonstrated in the literature that he can overcome these weaknesses. In this article, we will be using this technique with the pretrained neural network, AlexNet, which had been previously trained with the ImageNet database. Our method doesn’t require a high amount of input data and thus saves a lot of time in retraining the network in another task, which can be related or unrelated to the source task. In fact, the prediction model was successfully adapted to the bearings diagnosis case. It showed also high degree of robustness against changes of functioning conditions.

Nowadays urban residents, especially ones in the city are more aware of air quality and how it can affect their health. Due to the limitation of spare sense nodes, the air quality information is very coarse in resolution that is not greatly understood nor accepted by the community. The demand for better resolution, information and prediction of air quality in these areas has brought us to this solution. Our proposed system gives us a real-time and fine-grained data map of the air quality in the city by using crowdsourced automobiles as well as their built-in sensors, which significantly improves the feasibility and practicability of the system in a more dynamic way. By using LoRa WAN network, we can increase the range without worrying about the amount of sensor data to be transmitted. Once the data from the sensors is obtained, it is sent to the cloud through a base station where the data is processed using various algorithms and a fine-grained air quality pollution map of the city is generated to help understand the air pollution levels properly.

In this article, we propose a new clustering algorithm namely an efficient social spider optimization for data clustering using data vector representation (ESSODCDI). It uses a data vector representation for each spider so that its memory requirements can be reduced. Unlike other nature-inspired algorithms, it requires lesser memory requirements. We find that its clustering results are by far better than those of other nature-inspired algorithms.

La tecnica Personal Event è lo strumento applicativo del sistema di organizzazione “dal basso” nel quale il personale dell’azienda viene formato e accompagnato nella gestione del sistema organizzativo e amministrativo contabile affinché l’assetto organizzativo definitivo sia allineato all’obiettivo di produrre profitto in maniera duratura attraverso la gestione dei fattori di rischio individuali consoni alla mansione svolta in concreto dalla persona; questa responsabilizzazione individuale insegna alla persona a lavorare per obiettivi e progetti anziché per orari e mansioni, nel corso della formazione il personale diventa parte attiva nella formulazione delle procedure operative e vengono quindi concretamente fondate sui reali oggetti/rischi gestiti dal lavoratore in funzione del complesso sistema aziendale; questo modo di impostare la relazione con il lavoratore è molto fruttuosa ed è lo step preliminare per attuare lo Smart Working in maniera
veramente produttiva per l’impresa.
Oorsig van faseveranderingsmateriaal vir sub-zero temperatuurtoepassings in verkoelingsvervoer
Authors: Ndanduleni C , Huan Z
Published: April 2020

Hierdie artikel bied ’n oorsig van die tradisionele gebruik van faseveranderingsmateriaal (FVM) in verkoelingsvervoer. Die meerderheid faseveranderingsmateriale in bouwerk en konstruksie word vir ruimtelike verwarming en verkoeling, kweekhuis-verhitting, kook met sonkrag, en die berging van son-energie vir waterverhitting gebruik. Daar is egter ’n merkbare afwesigheid van literatuur oor die aanwending van faseveranderingsmateriaal vir gebruik om bevrore voedselprodukte te bewaar. Hierdie oorsig fokus op latente hittebewarings (LHB) materiale se gebruik in padvervoer by ’n lae temperatuur (sub-zero), en van die voordele vir die verkoeling van bederfbare voedsel oor kort- en lang-afstande. Die voordele van die gebruik van latente hitte-bewaringsmateriaal, eerder as ’n konvensionele meganiese verdampings-kompressiesisteem, word ondersoek met die klem op die omgewingsimpak en moontlike langtermyn nadele. Die studie fokus ook op die noodsaaklikheid om nuwe faseveranderingsmateriaal met hoë termiese siklusse en minimale degradering te ondersoek, ten einde die suksesvolle gebruik in verkoelingsvervoer oor die langtermyn te verseker. Kriteria vir die seleksie van toepaslike faseveranderingsmateriaal word opgesom, en ’n klassifikasie van faseveranderingsmateriaal, gebaseer op smelttemperature en latente warmte, word getabuleer. Faseveranderingsmateriaal en die oordrageienskappe daarvan is ontleed ten einde die eienskappe van faseveranderingsmateriaal op te som, en die akkuraatheid van elke navorsingstegniek word beoordeel op grond van soortgelyke studies wat deur ander navorsers publiseer is. Die faseveranderingsmateriaal wat in verkoelingsvervoer gebruik word, is empiries ontleed, en termiese-fi siese kriteria wat noodsaaklik is vir verskillende toepassings is ook onder die vergrootglas geplaas.

Published: April 2020

Purpose:  To determine the reliability of direct ophthalmoscopy and Non-Mydriatic fundus photography for screening of Diabetic Retinopathy by optometrist.

Study Design:  Observational, cross sectional.

Place and Duration of Study:  Al-Ibrahim eye hospital, Karachi from October to December 2018.

Material and Methods:  All individuals with type 2 diabetes of≥ 40 years of age were screened for diabetic retinopathy (DR) by two trained optometrists and an ophthalmologist. First Optometrist used Non Mydriatic Fundus Camera (NMFC) and second optometrist used direct ophthalmoscopy (DO) after dilating the pupils. Final examination was done by the Ophthalmologist with slit lamp using Volk fundus lens which was considered as reference standard. Every investigator was kept unaware of the findings of others.

Results:  A total of 698 eyes of 349 respondents were screened. Ophthalmologist could not make decision by bio microscopy in 44 (6.3%) individuals as compared to 128 (18.3%) by 1st optometrist by NMFC and 142 (20.3%) by 2nd optometrist with DO. Diabetic retinopathy (DR) was diagnosed in 1493 (21.4%) with slit lamp, in 1172 (16.8%) with NMFC and in 1333 (19.1%) with DO. Sensitivity of NMFC was 76% and that of DO was 64.8%. Specificity of NMFC was 97.45% and that of DO was 96.63%.  Positive predictive value (PPV) of NMFC was 89.33% and that of DO was 84.3% Negative predictive value (NPV) of NMFC was 93.33% and that of DO was 90.7%.

Conclusion:  NMFC is recommended tool for DR screening; but DO by well-trained optometrist can be reliable where neither ophthalmologist nor NMFC is available.
Clear Lens Extraction in Glaucoma (Is it still a controversy?)
Authors: Ahmad Syed Shoeb
Published: April 2020

The lens appears to play a strategic role in the etiopathogenesis of glaucoma. This is not a new concept. In 1891 Priestley Smith had noted that some patients diagnosed with glaucoma demonstrated shallow anterior chambers even before the development of the disease (glaucoma). He concluded that this feature could be attributed to the disproportion between the size of the eyeball and the lens1. Lowe (1969) mentioned that the anatomical basis of primary angle closure glaucoma (PACG) lies in two important “constitutional” factors (lens position and thickness) and two other factors of lesser importance related to advanced age (increase in lens thickness and anterior lens displacement)2.

Purpose:  To study the current practice patterns of pediatric ophthalmologists in the management of strabismus in Punjab.

Study Design:  Questionnaire based Practice pattern survey.

Place and Duration of Study:  Teaching hospitals of Punjab from July 2018 to July 2019.

Material and Methods:  This study was conducted at ophthalmology departments of various teaching hospitals of Punjab. A questionnaire was designed to find out the current practice pattern for management of strabismus. Ophthalmologists who were members of Ophthalmological Society of Pakistan (OSP), having their expertise in strabismus surgery for more than 5years and practicing pediatric ophthalmology were selected. Discussion was also held regarding questionnaire and practices being performed after filling the proforma. This data was compiled, analyzed and was converted to a summary in points.

Results:  We contacted 90 ophthalmologists out of whom 76 responded to our Questionnaire. Complete Orthoptic Assessment was performed by only 46% (35) of the ophthalmologists. Prism cover test was used as a diagnostic tool by 70 (92%) ophthalmologists. Rest of the ophthalmologists used Synoptophore with it. Percentage of ophthalmologists performing cycloplegic refraction was very low.  Only 5 (6.57%) surgeons used adjustable sutures. Only 46% of surgeons used to explain the complications of Anesthesia. More than 90% of surgeons explained the surgical procedures being done, its complications, post-operative care and need to use glasses or need for orthoptic exercises. All the surgeons kept follow up of the patients on 1st post-operative day.

Conclusion:  The current practices in strabismus need to be standardized and a consensus should be developed at a national level.

Pada umumnya pemahaman Tim Pelaksana Kegiatan (TPK) Dana Desa, Tukang, dan Pemerintah Desa di Kabupaten Minahasa Selatan, dalam menghitung Rencana Anggaran Biaya (RAB) suatu bangunan tidak memahami asas ilmiah dalam analisis dan desain suatu bangunan. Dalam melaksanakan pekerjaan rumah tinggal, Tanggul, Bronjong, Jalan Setapak, dll, biasanya besarnya harga pekerjaan hanya dilakukan dengan penaksiran. Hal ini dilakukan karena kurangnya pengetahuan para tukang tentang bagaimana cara menghitung anggaran biaya suatu bangunan, misalnya berapa banyaknya bahan bangunan yang akan digunakan dan jumlah tenaga kerja. Akibat kurangnya pengetahuan tersebut, maka dapat mengakibatkan kerugian bagi kedua belah pihak baik pemilik bangunan maupun pelaksana pekerjaan itu sendiri.Pelatihan dilakukan dengan metode ceramah dan demonstrasi. Ceramah digunakan untuk menyampaikan konsep tentang: (a) Tujuan dan fungsi dari pembuatan RAB bangunan, (b) Unsusr-unsur yang terlibat dalam pembangunan, (c) Persiapan pelaksanaan pekerjaan (Peraturan dan mekanisme IMB), (d) peraturan-peraturan dalam pelaksanaannya untuk mengendalikan jalannya pekerjaan, dan (e) Menyusun RAB bangunan. Demontrasi dilakukan  oleh  tim  pengabdi  sebagai  narasumber, yaitu dengan memberikan contoh cara membuat dan menghitung RAB bangunan.Hasil pelaksanaan kegiatan pengabdian dapat disimpulkan bahwa: (1) kegiatan pengabdian dapat meningkatkan pengetahuan tentang teknik perancangan dan analisis anggaran biaya suatu bangunan, dan (2) untuk lebih meningkatkan pengetahuan cara mengatasi permasalahan dalam perancangan dan analisis anggaran biaya suatu bangunan. Kegiatan pengabdian secara keseluruhan dapat dinilai baik dilihat dari 4 (empat) komponen, yaitu: keberhasilan target jumlah peserta pelatihan (104%), ketercapaian tujuan pelatihan (80%), ketercapaian target materi yang telah direncanakan (80%), dan kemampuan peserta dalam penguasaan materi (60%). Kata  kunci:  Pelatihan, Teori Menghitung RAB,  Tim Pelaksana Kegiatan (TPK) Dana Desa, Tukang, Pemerintah Wanga Amongena.

PROBLEMS OF APPLICATION OF THE RIGHT TO DATA PORTABILITY
Authors: Kive Marta
Published: April 2020

The aim of the publication is to analyze the advantages and disadvantages of the right to data portability, as well as to look at them in the context of development of a legal framework for the protection of personal data. The General Data Protection Regulation entered into force on 25 May 2018 and introduced a new legal framework for the protection of personal data in the European Union, and also included several new rights, including the right to data portability. These are rights of the data subject to receive personal data concerning himself, which he has provided to the controller, in a structured, widely used and machine‐readable format, and transmit this information to another controller, if it is possible. The right to data portability applies only to personal data provided by the controller to the data subject himself, and only if the processing was initially based on the consent of the user or on the basis of a contract. This means that the right to data portability is not feasible when data processing is based on another legal basis. In the context of the right to data portability, data subjects directly transmit data from one data controller to another where technically possible. The regulation does not specify what is meant by “technically feasible”. The wording indicates that this should be addressed on a case‐by‐case basis and a dynamic interpretation of the term “technically feasible” should be ensured. This is limited because the Regulation does not oblige data controllers to accept or maintain compatible processing systems.

The purpose of this article is to describe the motivation structure of IT professionals in Latvia from two points of view: from the point of view of IT specialists themselves and from the point of view of HR managers working on attracting and managing IT specialists.
The theoretical foundation of this approach is based on McClelland theory of learned needs. This study uses theoretical approach, focused on understanding of individuals’ needs and considering people’s achievements as the main motivational factor. According to this theory, in order to motivate an employee to work efficiently and maintain his devotion to the company, it is necessary to understand his unsatisfied need and offer opportunities for its constant satisfaction.
The results of the research show that IT professionals are a group of people whose needs for achievements and needs for belonging dominate. Needs for power are presented slightly. For effective management of this professional group, managers should create comfortable conditions for them. Minimize control, focus on what people do, not how they do it. Provide very accurate information about the project goals, restrictions, stages and deadlines. Clearly formulate expectations of labour productivity and obtained results, minimize routine connected with reports.

To resolve the issues of the conventional dust removing method, such as electrostatic suspension and direct wiping with special lens paper, which can cause damage to precision instruments and their dependence on specific dust particle properties, we present a novel acoustic-levitation device design which incorporates an initial design of a multi-axis levitation device by Marzo. A. with our enhancement model based on the variation of transducers numbers and their spacing to achieve the dust removing efficiency and feasibility in real dust removal process. In this work, modeling simulation in COMSOL Multiphysics and light absorbance experiment are performed to evaluate the distribution of acoustic fields, trajectory of dust particles, and dust removing efficiency. With the manufactured device based on our design, the varying factors are characterized that may influence the removing efficiency when output voltage generated onto motor driven board is altered. Experiment shows 27.5 V is the most efficient voltage output with highest dust removal proportion in actual removing operations. The study demonstrates our design can achieve higher dust removing efficiency comparing to conventional methods. Whereas our design serves the purpose to solve a practical industrial problem, this paper also shows how it can be taken into the classroom as an demonstration experiment, providing an animated way to visualize the nodes and antinodes by the levitation position of particles, which help the students to not only understand the physical properties of standing waves, but also the connection from a classroom lab to an industrial solution.

Cryptography is one of the technological means to provide security to data being transmitted on information and communication systems. When it is necessary to securely transmit data in limited bandwidth, both compression and encryption must be performed. Researchers have combined compression and encryption together to reduce the overall processing time.
In this paper, new partial encryption schemes are proposed to encrypt only part of the compressed image. Soft and hard threshold compression methods are used in the compression step and the Advanced Encryption Standard (AES) cipher is used for the encryption step. The effect of different threshold values on the performance of the proposed schemes are studied. The proposed partial encryption schemes are fast, secure, and do not reduce the compression performance of the underlying selected compression methods.
Region-Based Fractional Wavelet Transform Using Post Processing Artifact Reduction
Authors: Abdul-Jabbar Jassim , Taqi Alyaa
Published: April 2020

Wavelet-based algorithms are increasingly used in the source coding of remote sensing, satellite and other geospatial imagery. At the same time, wavelet-based coding applications are also increased in robust communication and network transmission of images. Although wireless multimedia sensors are widely used to deliver multimedia content due to the availability of inexpensive CMOS cameras, their computational and memory resources are still typically very limited. It is known that allowing a low-cost camera sensor node with limited RAM size to perform a multi-level wavelet transform, will in return limit the size of the acquired image. Recently, fractional wavelet filter technique became an interesting solution to reduce communication energy and wireless bandwidth, for resource-constrained devices (e.g. digital cameras). The reduction in the required memory in these fractional wavelet transforms is achieved at the expense of the image quality. In this paper, an adaptive fractional artifacts reduction approach is proposed for efficient filtering operations according to the desired compromise between the effectiveness of artifact reduction and algorithm simplicity using some local image features to reduce boundaries artifacts caused by fractional wavelet. Applying such technique on different types of images with different sizes using CDF 9/7 wavelet filters results in a good performance.

The present study was conducted to investigate the effectiveness of the aqueous extract of Artemisia arborescens to reduce the effects of Aluminium chloride (AlCl3) on lipid parameters, blood pressure and on histological archi-tecture of sections from liver and heart of rats. Forty-eight female Wistar rats weighting 125±25g were randomly divided into four equal groups of twelve rats each. The animals were given a dose of (AlCl3) (20mg.k-1.bw) three times a week intraperitoneally and the aqueous extract of A.arborescens orally (200mg.L-1) for 06 weeks. Total cholesterol, triglycer-ides, phospholipids, HDLc, LDLc, and LDH were measured in serum and total cholesterol, triglycerides, phospholipids, TBARS in liver. The blood pressure was also recorded. Results revealed that AlCl3 caused an increase in total cholesterol and triglycerides levels, LDLc, Tchol/HDLc Ratio and LDH in serum and total cholesterol, triglycerides and TBARS in liver; however, HDL in se-rum and phospholipids in serum and hepatic tissue were decreased. AlCl3 caused elevation of the diastolic and systolic arterial blood pressure of rats and caused hepatocytic degenerations, necrosis and severe vascular conges-tion in liver, in addition to disruption of the myocardial fibers, necrosis of myocardial cells and congestion of inter-muscular capillaries in heart, while the aqueous extract of A.arborescens ameliorates these effects near to their normal values. This study suggested that the aqueous extract of A.arborescens showed lipid-lowering and hypotensive effects that protect the liver and heart against aluminium toxicity and that could possibly restore the altered hepatic and cardiac cells organization in rat intoxicated with aluminium.
