Kontrol Presentasi Telapak Tangan Menggunakan Haar Cascade Classification

Presentasi yaitu suatu kegiatan yang dilakukan sebagai penyampaian ilmu oleh pengajar untuk memberitahukan hasil penelitian serta gagasan. Presentasi sudah menjadi aktivitas yang dilakukan di hampir semua bidang pekerjaan sehari-hari.Untuk melakukan presentasi, dibutuhkan sebuahkomputer, mouse, dan keyboard sebagai alat bantu dan sarana untuk menjalankan slide presentasi. Selain dibutuhkan alat bantu presentasi, saat presentasi juga dibutuhkan seseorang operator untuk mengendalikan komputer saat presentasi berlangsung. Dengan melihat kondisi tersebut, dibutuhkan teknologi yang dapat mengintegrasikan berbagai macam fungsi alat bantu presentasi dan pengendali komputer saat presentasi. Deteksi telapak tangan pada penelitian ini memakai bahasa pemrograman python dan juga sebuah library OpenCV untuk proses inputan. Metode yang digunakan untuk mendeteksi gerakan telapak tangan menggunakan metode Haar Cascade Classifier. Metode Haar Cascade Classifier dapat digunakan untuk mendeteksi objek telapak tangan dan mampu mengontrol slide dengantelapak tangan dengan webcam secara real time. Dalam pendeteksian harus ditentukan centroid agar dapat diketahui jumlah frame untuk memindahkan slide serta jarak dari webcam ke objek juga dapat mempengaruhi dalam mengontrol presentasi. Namun, sistem ini memiliki banyak kelemahan dan harus diperbaiki. Sensitifitas pendeteksian yang tidak terlalu baik yang dapat dipengaruhi oleh beberapa faktor yaitu webcam yang kurang bagus, spesifikasi Personal Computer (PC) rendah, dataset yang meyebabkan false negative, serta pencahayaan ataupun pengaruh dari background.
IOT based Smart Integrated Medical Health Monitoring System

:- India is one of the most populous countries of the world. Due to over population, ignorance of health have been remained the major problems in India. For every one minute a death swoops in because of unpredictable and unexpected accidents. To save a life is auspicious as well as precious. The idea here is to provide an intelligent smart health system (IMHS) using some sensors and microcontrollers which are implemented in stretcher. It will sense the body condition and send the data to the hospital and also informs to nearby police station where accident occurs to avoid law issues through server. If this system is implemented, many human lives can be saved by preparing intensive care unit in hospital, as their physical parameters are updated to hospital before their arrival to hospital.

Size- and Structure-lnsensitivity of the Thermophoretic Transport of Aggregated “Soot” Particles in Gases

Abstract There is now convincing theoretical and experimental evidence, assembled and discussed here, for the remarkable insensitivity of the orientation-averaged thermophoretic properties of aggregated particles to aggregate size and structure (morphology), as well as the nature of gas/surface scattering. Indeed, theoretical consideration of straight chains, and uniformly “packed” quasi-spherical agglomerates, as well as recent experimental data on soot aggregate transport in/from laminar flames at atmospheric pressure, indicates that the orientation-averaged thermophoretic diffusivity, (αTD)n, of an aggregate containing N primary particles is usually within about 8% of the (αTD)i,-value for a single “primary” sphere in the free-molecule regime and within about 21 % in the continuum limit. Among other things, this implies that, especially in the free-molecule regime, thermophoretically-dominated transport rates can be adequately predicted without a detailed knowledge of the size and morphology (-distribu.
Biocompatible, Luminescent Silver@Phenol Formaldehyde Resin Core/Shell Nanospheres: Large‐Scale Synthesis and Application for In Vivo Bioimaging

Biocompatible and green luminescent monodisperse silver/phenol formaldehyde resin core/shell spheres with controllable sizes, in the range of 180 to 1000 nm, and interesting architectures (centric, eccentric, and coenocytic core/shell spheres) have been synthesized by a facile one‐step hydrothermal approach. These spheres can be used as bioimaging labels for human lung cancer H1299 cells. The results demonstrate that the nanoparticles can be internalized into cells and exhibit no cytotoxic effects, showing that such novel biocompatible core/shell structures can potentially be used as in vivo bioimaging labels. This facile one‐pot polymerization and encapsulation technique may provide a useful tool to synthesize other core/shell particles that have potential application in biotechnology.
Sentiment analysis of the Saudi Digital Library (SDL) tweets interactions

In July 2011, the Saudi Digital Library (SDL) created a Twitter account to serve as a primary means for customer interaction, support, and a Q&A page. The SDL account actively tweets about SDL news, recently-added databases, and training venues, dates, and times. It is interesting to see SDL users interact with the SDL account on Twitter, but how beneficial is it? This study investigates the reactions of people who use the SDL to SDL tweets via Twitter, using a manual sentiment content analysis approach to analyze the interactions. The content analysis consists of counting the number of likes and retweets, whether the questions posted receive answers, and lastly categorizing the sentiment expressed in tweets as “positive,” “negative,” and “neutral. ” The students’ interaction with SDL through Twitter ranges between positive and neutral. Students seem to like tweets about news and instructions about the SDL. However, students do not seem to find solutions to the problems they are having; instead, they are directed elsewhere to find help.
Interrelationships Between Patients’ Data Tracking Practices, Data Sharing Practices, and Health Literacy: Onsite Survey Study

Background Although the use of patient-generated data (PGD) in the optimization of patient care shows great promise, little is known about whether patients who track their PGD necessarily share the data with their clinicians. Meanwhile, health literacy—an important construct that captures an individual’s ability to manage their health and to engage with their health care providers—has often been neglected in prior studies focused on PGD tracking and sharing. To leverage the full potential of PGD, it is necessary to bridge the gap between patients’ data tracking and data sharing practices by first understanding the interrelationships between these practices and the factors contributing to these practices. Objective This study aims to systematically examine the interrelationships between PGD tracking practices, data sharing practices, and health literacy among individual patients. Methods We surveyed 109 patients at the time they met with a clinician at a university health center, unlike prior research that often examined patients’ retrospective experience after some time had passed since their clinic visit. The survey consisted of 39 questions asking patients about their PGD tracking and sharing practices based on their current clinical encounter. The survey also contained questions related to the participants’ health literacy. All the participants completed the survey on a tablet device. The onsite survey study enabled us to collect ecologically valid data based on patients’ immediate experiences situated within their clinic visit. Results We found no evidence that tracking PGD was related to self-reports of having sufficient information to manage one’s health; however, the number of data types participants tracked positively related to their self-assessed ability to actively engage with health care providers. Participants’ data tracking practices and their health literacy did not relate to their data sharing practices; however, their ability to engage with health care providers positively related to their willingness to share their data with clinicians in the future. Participants reported several benefits of, and barriers to, sharing their PGD with clinicians. Conclusions Although tracking PGD could help patients better engage with health care providers, it may not provide patients with sufficient information to manage their health. The gaps between tracking and sharing PGD with health care providers call for efforts to inform patients of how their data relate to their health and to facilitate efficient clinician-patient communication. To realize the full potential of PGD and to promote individuals’ health literacy, empowering patients to effectively track and share their PGD is important—both technologies and health care providers can play important roles.
Towards the Successful Adoption of MOOCs in Libyan Higher Education: A Case Study of the University of Misurata

This paper focuses on the adoption of Massive Open Online Courses (MOOCs) in the Libyan university environment. MOOCs have become a much-discussed phenomenon in the online learning world, and can provide learning opportunities for large numbers of students from anywhere, as long as they can access the course materials through the Internet. With the growing trend towards online education, implementation models have become important to examine the factors affecting adoption processes. Although MOOCs are of growing importance in Higher Education Institutes (HEIs) in general, their adoption and implementation still face many challenges in Libya. The aim of this paper is to establish the existing level of adoption of MOOCs in one Libyan university, and identify the factors that are impeding the take-up of this form of education. The research adopts a qualitative approach, focusing on a case study of the University of Misurata, where a survey and interviews were undertaken. This has produced new insights that can guide future strategy and operational plans for adopting or improving existing MOOCs adoption processes in Libya. A multi-dimensional model was used to map and assess the MOOC adoption process. The research findings can benefit online learning facilitators and policymakers by increasing the successful implementation of MOOCs.
Dynamics of Predator‐Prey Interactions in Continuous Cultures

This paper studies the behavior of a general unstructured kinetic model for continuous bioreactors involving interactions between predator, prey and a limiting substrate. The analysis carried out in this paper shows how closed analytical conditions for arbitrary growth rates can be derived that describe the conditions for the existence of the interacting species in an oscillatory behavior. It is also demonstrated how practical diagrams in terms of operating and kinetic parameters can be constructed that classify the different behavior predicted by the model. Applications of these general results to a number of experimentally validated models have revealed that the saturation model always predicts hard oscillations for a certain range of dilution rates, for any values of model parameters. Bifurcation diagrams in the operating parameter space permitted the delineation of regions of hard oscillations, regions of static coexistence, regions of predator washout and regions of total washout. The analysis of the double saturation model has proven its ability to predict two Hopf points. Hard oscillations are therefore expected within the dilution rates corresponding to the two Hopf points. Practical diagrams were also constructed to delineate the boundaries separating hard oscillations from static coexistence and washout conditions.
Synthesis and Characterization of Chromium‐Doped Mesoporous Tungsten Oxide for Gas Sensing Applications

SBA‐15 (2D hexagonal structure) and KIT‐6 (3D cubic structure) silica materials are used as templates for the synthesis of two different crystalline mesoporous WO3 replicas usable as NO2 gas sensors. High‐resolution transmission electron microscopy (HRTEM) studies reveal that single‐crystal hexagonal rings set up the atomic morphology of the WO3 KIT‐6 replica, whereas the SBA‐15 replica is composed of randomly oriented nanoparticles. A model capable of explaining the KIT‐6 replica mesostructure is described. A small amount of chromium is added to the WO3 matrix in order to enhance sensor response. It is demonstrated that chromium does not form clusters, but well‐distributed centers. Pure WO3 KIT‐6 replica displays a higher response rate as well as a lower response time to NO2 gas than the SBA‐15 replica. This behavior is explained by taking into account that the KIT‐6 replica has a higher surface area as demonstrated by Brunauer–Emmett–Teller analyses and its mesostructure is fully maintained after the screen‐printing step involved in sensors preparation. The presence of chromium in the material results in a shorter response time and improved sensor response to the lowest NO2 concentrations tested. Electrical differences related to mesostructure are reduced as a result of additive introduction.
Evidence for Ideal and Non-Ideal Equilibrium Freezing of Leaf Water in Frosthardy Ivy (Hedera helix) and Winter Barley (Hordeum vulgare)

Temperature dependences of leaf water potentials (ψleaf) of frozen leaves of frosthardy ivy and winter barley were determined psychrometrically and found to coincide with the respective water potentials of ice which were obtained using the same technique. The water potentials of ice showed good agreement with theoretically established data. Analysis of the components of ψ of frozen leaves of Hedera helix revealed ideal equilibrium freezing, i.e. the governing of the relative content of liquid (or frozen) water solely by the osmotic potential. In winter barley, by contrast, a negative pressure potential was demonstrated to contribute to ψleaf. even under conditions of moderate frost. This reduced the degree of protoplast dehydration and the extent to which the concentrations of the cellular solutes rose. Such a freezing behavior is termed non-ideal equilibrium freezing. Depending on the original content of leaf water, the volume increments of liquid water due to the negative pressure potential amounted up to 10% at −6 °C and even more at a lower temperature. In addition to the experimental data, a theoretical treatment of psychrometry at subzero temperatures is presented.
LC-ICPMS speciation of arsenite and arsenate oxyanion mixtures during their adsorption with dried sludge

This report describes the speciation of arsenic oxyanion mixtures using a liquid chromatography coupled with inductively coupled plasma mass spectrometry (LC-ICPMS) technique. The proposed method allowed a fast, sensitive and environmentally friendly determination of arsenic inorganic species in water. The speciation was carried out during adsorption experiments using dried sludge as an adsorbent. The dried used sludge was generated as discarded material from a water plant after coagulation and sedimentation stages and was selected due to its chemical and mineralogical composition. The sludge composition includes high proportions of silica, aluminium and iron minerals, which are known to be responsible for the adsorption of arsenic species. The As speciation results demonstrated a low limit of detection (LOD) of 5.26 ppb for arsenite and 9.85 ppb for arsenate species. The arsenate species was removed faster compared to the arsenite species when both are present as mixtures. These findings confirm that electrostatic interactions between the sludge components and charged H2AsO4−, arsenate predominant species at pH 6.0, result in a faster equilibrium than H3AsO3 (arsenite, a predominantly neutral species at pH 6.0). The adsorption was fitted by Langmuir and Freundlich models; the second one being the one which better represented the adsorption process. The Freundlich parameter k, the relative uptake capacity of the adsorbent, was 0.221 (mg g−1) (L mg−1)n for arsenite and 0.101 (mg g−1) (L mg−1)n for arsenate. The data from competitive adsorption tests suggested that the removal mechanism for arsenic species is due to the formation of an outer sphere complex via electrostatic or van der Waals attractions. The results show the capability of the dried sludge as a green alternative to remove trace levels of both arsenic oxyanions from contaminated or wastewaters. Also, the developed speciation protocol allowed a better understanding of the adsorption mechanism of arsenic species by Fe-rich sludge.
Naphthalene Diimide Incorporated Thiophene-Free Copolymers with Acene and Heteroacene Units: Comparison of Geometric Features and Electron-Donating Strength of Co-units

A family of naphthalene diimide (NDI)-based donor (D)-acceptor (A) copolymers with various acene- (benzene (Bz), naphthalene (Np), and pyrene (Py)) and heteroacene-type (selenophene (Se) and thiophene (Th)) donor rings has been designed and synthesized as a means to systematically understand structure–property relationships on the subject of the structural factor and electron-donating capability of the donor portions for applications in organic field-effect transistors (OFETs) based on NDIs. Alongside of two categories dealing with the lack or existence of the heteroatoms in the donor framework, the resulting copolymers can also be classified into ‘thiophene-free’ D–A copolymers (PNDI-Bz, PNDI-Np, PNDI-Py, and PNDI-Se) and thiophene-containing copolymer (PNDI-Th). The results from optical and electronic properties lead to the determination that the empirical electron-donating strength of donor co-units is in the order of Bz < Np < Py < Th < Se. In contrast with the similarity of the LUMO levels (−3.73∼−3.
Solution Phase Synthesis of Cu(OH)2 Nanoribbons by Coordination Self-Assembly Using Cu2S Nanowires as Precursors

Nanoribbons of Cu(OH)2 have been synthesized by coordination self-assembly in solution. Techniques of XRD, TEM, HRTEM, SEM, ED, EDX, and XPS have been used to characterize the morphology, structure, and composition of the nanoribbons. The Cu(OH)2 nanoribbons are 20−100 nm in width, several nm in thickness, and up to 100 μm in length. The basic building blocks of the coordination self-assembly are the square planar complexes of Cu2+, which are continuously supplied in a controlled manner from the Cu2S nanowires. NH3 serves as a molecular transporter in the nanoribbon assembly process. The advantages of our method for the nanoribbon synthesis lie in the low temperature and mild reaction conditions, which permit large scale production at low cost.

Hierarchical GOs/Fe3O4/PANI magnetic composites as adsorbent for ionic dye pollution treatment

Graphene oxides (GOs) decorated with Fe3O4 nanoparticles (GOs/Fe3O4) were modified by polyaniline (PANI). Selecting methyl orange (MO) as an organic pollutant model, the hierarchical GOs/Fe3O4/PANI magnetic composites showed high adsorption capacity toward MO (585.02 mg g−1), which was superior to that of other adsorbents. The nitrogen-containing functional groups of PANI decorated on GOs/Fe3O4/PANI provided numerous effective adsorption sites and thus increased the adsorption capacity for MO. Moreover, PANI protected the Fe3O4 nanoparticles from dissolution, and therefore improved the stability of GOs/Fe3O4/PANI in solution. The results show that the GOs/Fe3O4/PANI magnetic composites are promising magnetic nanomaterials for the preconcentration and separation of ionic dye pollutants from aqueous solutions for environmental pollution cleanup.
