DISPERSION COMPENSATION USING ELECTRONIC METHODS BROADCASTING SYSTEM
Authors:   University of Bujumbura, Vyukusenge Augustin
Published: October 2021

System distortions due to chromatic dispersion (CD), polarization mode dispersion (PMD), laser phase noise and fiber nonlinearities have a significant impact on the performance of high-speed fiber optic networks. In connection with the need to improve the quality of information transmission in high-speed fiber-optic communication systems, coherent detection with a digital signal processing unit is of particular interest. The main goal of the DSP block is to reduce the impact of linear and nonlinear effects that degrade the quality of information transfer. In this direction, the use of adaptive filters with adaptation algorithms for filter coefficients plays an important role. The Constant Modulus Algorithm (CMA) and the Least Mean Square (LMS) method used to compensate for dispersion distortions are presented. The load on transport networks based on fiber-optic transmission systems is increasing at an accelerating rate. This paper discusses the possibility and limitations of increasing the throughput of fiber-optic transmission systems by reducing the distance between carriers. A comparison is made between fixed and flexible grids in terms of the spectral bandwidth efficiency. It is concluded that the use of flexible mesh technology is promising when switching to channel speeds above 100 Gbit/s.
A 19 MW, 12.5 B, 2.1 MS/S SINGLE-BIT DS ADC IN 0.18 MM DIGITAL CMOS PROCESS

Published: October 2021

The increasingly stringent requirements of today’s communication systems and portable devices are imposing two challenges on the design of high-resolution, high-speed ADCs and delta-sigma modulators (DSMs) in particular. The first is the extension of the input frequency range to include applications where the input bandwidth exceeds the 1 MHz range, while maintaining a feasible sampling frequency. The challenge in extending the operational speed of DSMs is further rendered more complicated by the ever shrinking transistor dimension, and in turn, the supply voltage, hence the second challenge. To address those two challenges, the DSMs presented in this paper targets a minimum of 12 bits in resolution at 2 MS/s Nyquist conversion rate, while using a single 1.8 V supply and minimum power dissipation.A switched-capacitor (SC) DS ADC integrated circuit (IC) with output rate slightly exceeding 2 MS/s was successfully implemented in a 1.8 V, 0.18 mm standard CMOS process. The IC consists of a fourth-order, multi-stage (2-1-1), single-bit modulator sampled at an oversampling rate of 50 MHz. Special effort has been made to reduce the power consumption of the modulator through careful system-level modeling and synthesis of circuit specifcations. Experimental results reveal a 77.6 dB dynamic range while consuming 18.8 mW of power, making it the lowest power dissipation for output rates in excess of 2 MS/s.

Published: October 2021

Based on published data and experimental studies of formation regularities of aluminium hydroxide, a reproducible technique for synthesis of bayerite-structured aluminium hydroxide by precipitation was developed as a part of the creation of preparation technology of chromia-alumina dehydrogenation catalyst. A possibility of synthesis of high purity bayerite (above 90 wt.%) with different particle sizes depending on synthesis conditions was shown. A correlation between dispersion of the sediments and synthesis temperature was shown, the optimal precipitation temperature – which allows obtaining bayerite with a sufficiently large particle size and high purity – was found. Based on the experiments, a fundamental difference between technologies and products of precipitation by sodium hydroxide and aqueous ammonia was shown. The influence of duration of precipitation stages on the properties of sediments is analyzed from the standpoint of theory of relative supersaturation

In this manuscript, a facility location model was designed to support logistics operations, considering service distance limitations for demand fulfillment and a list of candidate locations within a supply chain. Consequently, an allocation model was designed using Mixed-Integer Linear Programming (MILP), in which a finite number of demand nodes could be satisfied by a set of supply nodes, considering not only the costs related to these locations but also restrictions aimed at improving the level of service based on distance. Besides, an integrated solution scheme was proposed that includes a macro in VBA language that calculates the distance between nodes using the web mapping service developed by Google Maps and solving the model through a branch and cut algorithm. Subsequently, a case study was executed where the supply operation of an important Colombian retail company is analyzed. The results reflected positive effects not only on costs but also on the prioritization of average distance traveled and on the satisfaction of store demand by distribution centers. Thus, the conditions in which the implementation of this model provides strategic benefits were verified, functioning as a tool to support decision making.

Computer vision algorithms play a vital role in developing self-sustained autonomous systems. The objective of the present work is to integrate the robotic system with a moving conveyor using a single camera by adopting a Gaussian Mixture Model (GMM) based background subtraction method. In this work, a simple web camera is placed above the work cell to capture the continuous images of the moving objects on the conveyor along with a jointed arm robot are connected to a microcontroller through the computer. The position of the object with time and its features are extracted from the captured image frames by subtracting its background using the Gaussian Mixture Model (GMM). The output images of GMM are further processed by image processing techniques to extract the features like shape, color, center coordinates. The extracted coordinates of objects of interest are used as input parameters to the controller to activate the base rotation of a joint arm robot to perform different manipulations. The developed algorithm is evaluated on an indigenously fabricated work cell integrated with a computer vision setup.

The car following behaviour of a driver is the process of following the drivers to create an adjustment in the leading vehicle behaviour. In a condition, where the traffic volume is in a free-flowing situation, the selection of vehicles speed is typically limited by some factors such as weather conditions, lighting, and road geometry features. This study aims to investigate the effects of climates on driver’s car following behaviour and speed flow relationships for highways in Kuwait. The case study was conducted at Road 40 in Kuwait using RTMS Sx-300 device which is known as a radar device particularly used for monitoring traffic. The data was gathered between the periods from 29th December 2018 to 5th January 2019 within winter. MATLAB code was written to analyse and classify the gathered data. Then, the models were built using R-software. The study depicts that nearly 24.87% of the vehicles move between 60 km/h and 69 km/hour. Additionally, the vehicles were segmented according to their types i.e., Truck, Small, Medium and Large Sized Cars, in order to find the impact of following pattern on the vehicle average. It has been found that no significant association remains amidst the type of following pattern and the headway. Ultimately, a liner regression of data was developed to calculate a liner equation that shows the average headway as an element of speed for sixteen diverse following patterns. It has been recognized that an association could be supposed in medium-sized and small-sized vehicles. It has been observed that headway average could be placed in a linear equation for large, medium, and small as well as truck vehicles. It is worthy to denote that when data is bigger, the exactitude of a study enhances. Findings from each model of liner regression has more than 80% confidence level. The models of regression are deliberated as statistically significant where, the R (square) figures lies amidst 0.99 till 0.6. As per the findings, speed is the key influencing factor for headway value. The type of car does affect headway with drivers behind Heavy Good Vehicles and cars at the similar speed. According to the data, cars are identified to keep more headway when behind Heavy Good Vehicles in contrast with when behind other cars. These results will help the drivers to understand their behaviour that are associated with car crashes. Thus, increase road safety awareness and reduce traffic congestion in Kuwait.

One of the local traditions in Banyubiru Village is “Gumbrekan Mahesa” which is commemorated once a year. Gumbrekan Mahesa's local wisdom is believed to be a form of gratitude for the residents for the harvest gift given by God Almighty. The urgency of this research is the need to study local wisdom, especially the attributes used by the village community of Kampung Kerbau Banyubiru as basic data for the development of cultural tourism and creative economic potential in Ngawi Regency. In addition, it also provides an overview of the value of cultural wealth in today's society and young generation. The aims of this research is to know the type, philosophy, and function of buffalo attributes in Gumbrekan Mahesa tradition. This research method is exploratory research, namely social research that aims to explain the concepts or patterns used. The primary data used are interview data and buffalo attribute observation data. Data analysis was carried out by interactive model analysis. The results showed that the attributes used in the Gumbrekan Mahesa tradition consisted of “Klothak, Pecut, Alu, Lesung, and teak leaf caping. The meaning and function of Klothak is as a marker when the buffalo is being herded in the forest and a medium of communication between the herder and the buffalo. Alu  and lesung have the meaning of a tool to process food with patience and responsibility. Alu  and Lesung are also used when herders get lost in the forest and bulfaloes are lost. Pecut is a tool to regulate the buffalo to run according to the direction of the shepherd which means to obey the leadership and the rules. Teak leaf caps are used by buffalo herders to protect themselves from heat and rain. This caping is also believed to be able to ward off lightning.

The current pandemic condition has a significant impact on all aspects of human life, including the education sector. Especially for universities, in the midst of situations where it is not possible to have face-to-face meetings with many people, a strategy is needed to increase the interest of prospective students who entrust their education to these universities. This is also a challenge for the Hindu Philosophy Study Program, STAH Negeri Mpu Kuturan Singaraja. As new study programs and universities, of course, a mature strategy is needed so that whatever is the strength of the Hindu Philosophy Study Program can be well socialized to the community. In addition, of course, the existing opportunities must also be maximized to overcome all existing threats. By using qualitative research methods, the data obtained were analyzed qualitatively to gain an in-depth understanding of the new student admissions strategy in the Hindu Philosophy Study Program at STAH Negeri Mpu Kuturan Singaraja during the pandemic.
A systematic review: The role of gender in staffs’ experience of working with adult survivors of sexual trauma
Authors:   Tees, Esk & Wear Valleys NHS Foundation Trust, UK., Woodhouse Abbey , Craven-Staines Sarah ,   Teesside University, UK.
Published: October 2021

Despite the vast amount of research being devoted to the field of sexual abuse and trauma, literature surrounding a gender informed stance is still very much in its infancy. This article presents a systematic review aiming to provide an impartial critical examination of relevant existing literature with the main aim of exploring the role of gender in staffs’ experience of working with survivors of sexual trauma. Electronic databases were searched online. Studies were eligible for inclusion if they investigated the experience and gender of staff working with adult survivors of sexual trauma. The exclusion criteria were studies that focussed on child and adolescent participants, and survivors with an intellectual disability. Eight studies were eligible for inclusion, and as such reviewed by authors; each highlighted the crucial role gender plays in the unique work between professionals and survivors of sexual trauma. Findings from the review highlighted gender as influencing interpersonal dynamics when focussing in on the client and/or the clinician. Clinician gender was felt to be particularly impactful and potentially detrimental should the gender of the professional be the same of that of the client’s historic abuser. Further societal stereotypes and perceptions of what connotes an abuse survivor has implications for working with male and female survivors of sexual trauma. As a result, there is potential for males being discouraged from making disclosures due to a subconscious reduced openness to males as survivors, rather than abusers. Increased empathy was found more often to be afforded to female survivors, with harsher punishments attributed to their abusers. Evidence was also suggested for the global adverse impact of working with this client group on professionals with an increased risk of vicarious traumatisation and burnout highlighted amongst clinicians. Limitations are highlighted in relation to the review’s ability to truly explore gender as the study only made reference to biological sex.
At What Price? Managing the Costs of Tolerating Corrupt or Criminal Partners in Stability Interventions
Authors:   Independent Researcher, Queensland, Australia, Jayawardena Rohan
Published: October 2021

States or coalitions may conduct intervention operations to stabilise weak or failing states. Intervening powers often use military or police forces to impose security while development agencies rebuild the affected state’s institutions, including the Rule of Law. However, recent experience suggests that interventions may perpetuate criminal conduct. This paper examines the NATO missions in Afghanistan and other interventions to suggest links between partnering with corrupt or criminal actors and subsequent setbacks in stabilisation. It then proposes strategies by which future intervention forces may mitigate the risks of perpetuating criminal conduct. The paper asserts that intervention forces may empower criminal actors inadvertently or deliberately. It suggests that criminal allies may offer apparent security gains, and command popular support; and may be the only allies available. However, it concludes that perpetuating crime and corruption undermines the legitimacy of the affected state’s government and the intervention force, and potentially enables state capture. These outcomes may perpetuate violence. The paper suggests that intervention forces may mitigate these risks by setting clear priorities, planning against all potential threats including organised criminals, linking aid to the achievement of governance objectives, delaying transition until the affected state’s institutions are ready, and conducting deep selection of future leaders.

BACKGROUND: Chronic malnutrition is a long-term health condition that has threatening effects on children’s health. Environmental enteric dysfunction (EED) is a subclinical disorder affecting the small intestine that may occur due to exposure to environmental pathogens and toxins.

AIM: The present research was intended to detect the value of fecal biomarkers of intestinal epithelial damage alpha-1anti-trypsin (AAT) and intestinal inflammation Myeloperoxidase (MPO) and Neopetrin (NEO), also to quantify their association with faltering growth in stunted and underweight children.

PATIENTS AND METHODS: This case–control study included 105 children with moderate malnutrition as a case group and 100 children of normal body weight and height as a control group. Quantification of fecal markers levels of intestinal permeability AAT and intestinal inflammation (NEO and MPO) along with serum micronutrients levels (iron and zinc) in children with malnutrition in comparison to controls.

RESULTS: Fecal markers of intestinal permeability AAT and intestinal inflammation NEO had statistically significant higher levels in children with malnutrition, while serum micronutrients (iron and zinc) had statistically significant lower levels in children with malnutrition.

CONCLUSION: Faltering growth is associated with elevated fecal markers of intestinal permeability AAT and intestinal inflammation NEO. EED may be a cause for faltering growth.

Authors: Shalganov Tchavdar , Stoyanov Milko , Traykov Vassil
Published: October 2021

This study presents data from the national electronic registry BG-EPHY on electrophysiologic (EP) cardiac ablations in 2019 and 2020. Material and methods. This is a retrospective study of a full two-year sample of the BG-EPHY registry. Sex and age distribution of the patients, number of ablations, electroanatomic mapping (EAM), irrigated ablations, distribution of different types of arrhythmia, intraprocedural success and complications are presented. Results. In 2019 four EP laboratories performed 1033 ablations in 652 men (63.1%) and 381 women, incl. 12 pediatric ablations (1.2%). EAM was used in 46.7% of the procedures, irrigation catheter was used in 52.2%, and cryocatheter – in 0.5%. The most common procedure was pulmonary vein isolation, followed by ablation for AV nodal reentrant tachycardia and typical atrial flutter. In 2020 five EP laboratories performed 835 ablations in 508 men (60.8%) and 327 women, incl. 8 pediatric ablations (1%). EAM was used in 50.9% of the ablations, irrigation catheter – in 54.5%, and cryocatheter – in 3.8%. The most common procedure was again pulmonary vein isolation. Ablation of typical atrial flutter was the second most frequently performed procedure, ahead of AV nodal reentrant tachycardia. In 2020 the number of ablations of accessory pathways also distinctly dropped by 37%. In both years the acute success was over 98%, and the complications were less than 2%. Conclusion. The national registry of electrophysiology collects systematically and continuously basic data on all cardiac ablations performed in the country. The structure of the EP service is remarkably similar to other European countries. Acute success is very high, while intraprocedural complications are rare. In 2020 the number of the ablations dropped by 19% as a consequence of the COVID-19 pandemic.

Published: October 2021

Atrial ﬁ brillation (AF) is the most common arrhythmia in adults and requires permanent anticoagulation in the presence of risk factors. Left atrial (LA) thrombus is found in a signiﬁ cant minority of patients despite anticoagulant treatment. We aimed to estimate the prevalence of LA thrombosis on uninterrupted oral anticoagulation (OAC) in AF patients and to determine associated demographic, clinical, echocardiographic and tomographic parameters. Material and methods: We present retrospective study of 702 hospitalizations in 582 patients (397 males, 68.2%) with AF and/or atrial ﬂ utter on uninterrupted OAC for at least 3 weeks, assessed for LA thrombosis with transoesophageal echocardiography and/or cardiac computed tomography. Probability value of p ‹ 0.05 was considered signiﬁ cant for all statistical analyses. Results: The prevalence of LA thrombosis was 6.2%, without signiﬁ cant difference between patients on direct OAC (DOAC) or acenocoumarol (VKA). Non-paroxysmal arrhythmia was signiﬁ cantly associated with LA thrombus, OR 0.369, 95% CI 0.159-0.857, p = 0.02. The proportion of patients on VKA with subtherapeutic INR was signiﬁ cantly higher (30.7%), than the proportion of patients receiving too low dose of DOAC (9.7%), OR 4.1, 95%, CI 2 CI 2.7-6.23, р ‹ 0.001. No association was found between the LA appendage morphology type and the presence of LA thrombus. During a median follow-up of 30 days new stroke/transitory ischemic attack (TIA)/systemic embolism (SE) was registered in seven patients (1.34%), none of them with LA thrombus. Conclusion: The prevalence of LA thrombosis in the studied cohort is comparable to the published data and seemingly had no association with the OAC type. The incidence of stroke/TIA/SE was low on uninterrupted oral anticoagulation during short-term follow-up and there was no association between the presence of LA thrombus and thromboembolic event on follow-up.

There are problems people don’t want to talk about, and one of them is incontinence in adults. This is a fairly common and delicate problem. It negatively affects human life. This most often applies to people with disabilities and bedridden patients. People have to change their usual way of life, give up their favorite activities, there is a constant need to stay at home. Walking, attending events are difficult. All this has a corresponding effect on the psychological health of a person. In such a situation, it is advisable to use diapers for adults. This is a modern hygienic product that is intended to make life easier for people suffering from various forms of incontinence. Diapers are similar in shape to baby diapers, but they are adapted to the size of an adult. This is a great option for the care of patients who are bedfast or in a wheelchair.
Mental Illness and Prisoners: Concerns for Communities and Healthcare Providers
Authors: Hoke Samantha
Published: October 2021

The United States prison system is the largest in the world. Mental illness is disproportionately represented within this system where half of all incarcerated individuals have a mental illness, compared to 11% of the population. Four of 10 inmates released from prison recidivate and are re-incarcerated within three years. A social hypothesis suggests recidivism is the result of compounding social factors. Mentally ill individuals often find themselves in less than ideal circumstances of compounding social factors such as illicit substances and unemployment. Prison life may provide improved social situations and a rehabilitating environment, yet corrections often fall short of meeting acceptable standards of healthcare. This article provides a brief overview of healthcare in the corrections environment and discusses factors that affect mental healthcare in prisons, such as characteristics of the prison population and social policy. The article also addresses factors impacting mentally ill persons who are incarcerated, including access and barriers to mental health treatment and efforts to reduce recidivism.
Nurses with Undiagnosed Hearing Loss: Implications for Practice
Authors: Spencer Cara , Pennington Karen
Published: October 2021

Hearing loss affects 36 million people in the United States of America, including 17% of the adult population. This suggests some nurses will have hearing losses that affect their communication skills and their ability to perform auscultation assessments, potentially compromising patient care and safety. In this article, the authors begin by reviewing the hearing process, describing various types of hearing loss, and discussing noise-induced hearing loss and noise levels in hospitals. Next, they consider the role of hearing in nursing practice, review resources for hearing-impaired nurses, identify the many costs associated with untreated hearing loss, and note nurses’ responsibility for maintaining their hearing health. The authors conclude that nurses need to be aware of their risk for hearing loss and have their hearing screened every five years.
À part égale, Boismortier, Duval, Mouret, Niel, Rameau, Rebel et Francœur : deux saisons d’opéra à Paris (1735-1737)
Authors: Legrand Raphaëlle
Published: October 2021

L’article se donne pour but d’analyser comme un corpus homogène les six opéras créés durant les deux saisons lyriques de l’Académie royale de musique de Paris, 1735-1736 et 1736-1737, en cherchant à mettre en lumière davantage les points communs que les différences. Il s’agit de deux ballets, Les Voyages de l’Amour de J. Bodin de Boismortier et Les Génies de Mlle Duval ; trois ballets héroïques, Les Grâces de J.-J. Mouret, Les Romans de J.-B. Niel et Les Indes galantes de J.-Ph. Rameau ; et d’une tragédie en musique, Scanderberg , de F. Rebel et F. Francœur. Ce corpus est abordé sous l’angle de l’intertextualité, intra-générique d’une part (sommeils, tempêtes, char tiré par des dragons, génies élémentaires), en relation avec l’actualité politique (guerre de Succession de Pologne) d’autre part. La structure générale des opéras est analysée à l’aide de l’outil de Rémy-Michel Trotier : l’architecture harmonique. L’influence du style italien est pensée en termes de « marqueurs d’italianité », d’italianisme comme artéfact et de transferts culturels.
Les mariages avec des étrangères en Asie de l’Est : trafic de femmes ou migration choisie ?
Authors: Bélanger Danièle
Published: October 2021

De plus en plus d’hommes d’Asie de l’Est se tournent vers l’étranger pour trouver une épouse. Les mariages dans lesquels l’épouse est née à l’étranger représentent 15 % du total des nouvelles unions à la fin des années 2000 à Taïwan, 8 % en Corée du Sud et 6 % au Japon. Le premier groupe d’épouses étrangères dans ces pays est originaire de Chine populaire. Les Vietnamiennes sont la seconde nationalité représentée en Corée du Sud et à Taïwan, et les femmes des Philippines au Japon. La quête d’une épouse à l’étranger vient de la difficulté pour les hommes d’en trouver une dans leur propre pays. Une partie croissante des femmes en effet n’acceptent plus la vie d’épouse et de mère dans sa forme actuelle, avec un partage des tâches inégal au sein du couple et souvent l’abandon de leur emploi. Elles préfèrent rester célibataires et actives. La grande majorité des épouses étrangères venant se marier dans ces pays le font de leur propre chef, et non sous la pression parentale, et leur objectif est à la fois de se marier et de migrer. Comme la plupart des migrants des pays en développement, les épouses étrangères espèrent ainsi pouvoir aider leur famille en envoyant de l’argent.
Berkeley: tres vías para el conocimiento de dios
Authors: Luis López Alberto
Published: October 2021

Je propose d’identifier trois voies pour la connaissance de Dieu ou de l’esprit infini chez Berkeley. Ces trois voies lui sont propres, mais les deux premières relèvent davantage de sa philosophie, reposant essentiellement sur des concepts tels que ceux d’« idée » ou de « monde sensible », tandis que la troisième trouve sa source dans la pensée théologico-religieuse et dans l’activité évangélisatrice de Berkeley, telle qu’elle s’est développée lors de son séjour en Amérique et dans son rôle de doyen et, plus tard, comme évêque. Ces trois voies, complémentaires quoique différentes, se fondent sur l’« analogie », un concept central permettant aux esprits finis de connaître Dieu.
Identifying the determinants of individual scientific performance: A perspective focused on AMO theory
Authors: Guerrero Alba Felix , Martin Alcazar Fernando , Sanchez Gardey Gonzalo
Published: October 2021

Purpose: The aim of this study is to empirically analyse how motivation and the opportunity to investigate enhance the direct relation between the researcher’s human capital and individual scientific performance.Design/methodology/approach: Following recent investigations of strategic human capital and the abilities-motivation-opportunity (AMO) theory, we propose a double quantitative-qualitative methodology to identify the determinants of individual scientific performance.Findings: Applying regression analysis to a sample of 471 Spanish academic researchers, we confirm the moderating role of a researcher’s motivation and opportunities.Originality/value: Drawing on the empirical evidence obtained, this work discusses the relevant determinants of scientific productivity, providing practical recommendations for research management and policy making.
Robustness of global attractors: Abstract framework and application to dissipative wave equations
Authors: Dashkovskiy Sergey , Kapustyan Oleksiy
Published: October 2021

We establish local input-to-state stability and the asymptotic gain property for a class of infinite-dimensional systems with respect to the global attractor of the respective undisturbed system. We apply our results to a large class of dissipative wave equations with nontrivial global attractors.

Drug nanocarriers have been continuously improved to promote satisfactory release control. In this sense, luminescent materials have become an alternative option in clinical trials due to their ability to monitor drug delivery. Among the nanocarriers, silica stands out for structural stability, dispersibility, and surface reactivity. When using ceramic nanocarriers, one of the challenges is their interaction and selectivity capability for organic molecules, such as drugs. In order to overcome such adversity, superficial modifications can be carried out to enable a higher affinity for the desired drug. Thus, the present study aimed to obtain silica nanoparticles (NPs) doped with low concentrations of europium (III) superficially modified by (3-aminopropyl)triethoxysilane (APTES) to assess their interaction with the model drug cloxacillin benzathine. This drug was chosen because it is part of the ampicillin family and is commonly used in several treatments. Near-spherical and homogeneous silica NPs were obtained via sol-gel synthesis, with particle sizes of approximately 21 nm. It was possible to verify the fluorescence capacity of the silica NPs when doped with europium (III) in a mole percent that varied from 0.5 to 3.0%. A 10% volume percent of APTES caused the silica nanoparticles to increase the degree of hydrophobicity, with a shift in the contact angle from 8° to 51°. After surface modification by APTES, the silica nanocarrier (10 g·L-1) achieved a satisfactory degree of CLOX incorporation (25 g·L-1), increasing the adsorptive capacity to values above 50%. Therefore, silica NPs doped with europium (III) in a low percent of 0.5% (mole) modified by APTES showed promising results as an alternative option for trials and clinical studies of drug incorporation.

Healthcare systems constitute a significant portion of smart cities infrastructure. The aim of smart healthcare is two folds. The internal healthcare system has a sole focus on monitoring vital parameters of patients. The external systems provide proactive health care measures by the surveillance mechanism. This system utilizes the surveillance mechanism giving impetus to healthcare tagging requirements on the general public. The work exclusively deals with the mass gatherings and crowded places scenarios. Crowd gatherings and public places management is a vital challenge in any smart city environment. Protests and dissent are commonly observed crowd behavior. This behavior has the inherent capacity to transform into violent behavior. The paper explores a novel and deep learning-based method to provide an Internet of Things (IoT) environment-based decision support system for tagging healthcare systems for the people who are injured in crowd protests and violence. The proposed system is intelligent enough to classify protests into normal, medium and severe protest categories. The level of the protests is directly tagged to the nearest healthcare systems and generates the need for specialist healthcare professionals. The proposed system is an optimized solution for the people who are either participating in protests or stranded in such a protest environment. The proposed solution allows complete tagging of specialist healthcare professionals for all types of emergency response in specialized crowd gatherings. Experimental results are encouraging and have shown the proposed system has a fairly promising accuracy of more than eight one percent in classifying protest attributes and more than ninety percent accuracy for differentiating protests and violent actions. The numerical results are motivating enough for and it can be extended beyond proof of the concept into real time external surveillance and healthcare tagging.
