Authors: K.S. Sriranjani , K.V. Rajeshwara
Published: February 2021

BACKGROUND Surgical site infections (SSI) represent a significant hurdle in the recovery and return to normalcy of patients. When considering abdominal surgeries in particular, SSI and its complications have been identified as one of the most important causes for postoperative morbidity. Treatment of SSI’s ideally begins with prevention and this can be done with the identification of risk factors. This allows for appropriate stratification and institution of steps to safeguard the patient against the development of SSI in the pre-surgical period. The objectives of the study were to compare the incidence, severity and microbiological profile of surgical site infections following emergency and elective abdominal surgeries. METHODS This study was a prospective observational study, conducted from December 2017 to May 2019 at Father Muller Medical College Hospital, Mangalore, among patients who underwent laparotomy (regardless of indication) in either an elective or emergency setting. Patients who had SSI were then stratified using the ASEPSIS wound scoring system and the Southampton wound assessment scale. The type of SSI was further documented in each patient. Other parameters such as duration of stay in the hospital, microbiological profile, interventions performed etc. were also recorded in the study. RESULTS 150 patients were enrolled in the study (84 female and 66 male), 23 patients (incidence of 15.33 %) developed an SSI (7 elective cases and 16 emergency cases), whereas 127 did not. Of the organisms cultured, the most common was found to be coagulase negative staphylococcus (CoNS, 7 cases) followed by E. coli (4 cases). CONCLUSIONS The following factors were found to significantly contribute to the development of SSI - nature of the surgery, i.e. elective vs. emergency (P-value 0.040), class of wound (Pvalue 0.001), underlying malignancy (P-value 0.030) and a concomitant urinary tract infection (UTI) (P-value 0.045). The following factors were not found to contribute to the development of a SSI - sex of the patient (P-value 0.108), age of the patient (Pvalue 0.699), presence of diabetes mellitus (DM) (P-value 0.816), chronic kidney disease (CKD) (P-value 0.904) and acute respiratory infection (ARI) (P-value 0.909).
Fabrication of Ocular Prosthesis for Phthisis Bulbi by an Innovative Impression-Less Technique - A Case Report
Authors: Shetty Sanath , Sarfaraz Hasan , Shetty Naresh , Ahmed Syed Ghouse
Published: February 2021

Phthisis bulbi is an ocular condition caused by wound healing secondary to severe trauma, inflammation, or necrotising tumours of the eye. It represents an ocular endstage disease characterised by atrophy, shrinkage, disorganisation of the eyeball, and intraocular contents. Disfigurement associated with the eye can cause significant physical and emotional disturbance. Prosthetic rehabilitation over the residual eyeball is the preferred treatment of choice over surgical intervention such as enucleation or evisceration. Treatment of such patients is challenging and a multidisciplinary approach is required to provide a satisfactory ocular prosthesis. This case report describes the prosthetic management of a patient with phthisis bulbi by a novel impression-less technique. The initial unsaid communication that takes place between two individuals is through their “eyes”. A confident person will always maintain eye contact while conversing. They are the organs of the visual system which are sensitive to various stimuli.1 Any anomaly involving the eyes causes psychological, emotional, and aesthetic trauma to the patient. Phthisis bulbi is an ocular condition due to multifactorial conditions such as delayed wound healing secondary to severe trauma, infections such as keratitis, uveitis and endophthalmitis. Also, some failed surgical procedures including cataract, glaucoma, retinal surgery and intraocular malignancies like choroidal melanoma, retinoblastoma as well as systemic diseases like diabetes or hypertension may result in phthisis bulbi.2,3 The name “Phthisis bulbi” comes from a Greek word which means “to waste away” or “shrinkage. It is a histopathological diagnosis of end-stage non-functional ocular disease showing atrophy, shrinkage, and disorganisation of the eye and intraocular contents. Clinically, the eyes have no perception of light due to intraocular calcium deposition within band keratopathy, cataractous lens, sclera, gliotic neural retina, or within an optic nerve in the phthisical eye.4 Surgical procedures are not desired in a patient of phthisis bulbi unless it becomes painful. Hence, prosthetic rehabilitation is the only preferred treatment of choice in the patient with phthisis bulbi.5 A properly fabricated custom-made prosthesis enhances the patient's comfort, confidence, and aesthetics by increased adaptiveness, natural appearance, and functional stimulation.6 Hence, we devised an innovative approach to fabricate an ocular prosthesis for a patient suffering from phthisis bulbi by using an impression less technique which has been described in this case report.

Authors: Nurbaeva K. S. , Cheldieva F. A. , Shumilova A. A. , Lila A. M. , Reshetnyak T. M.
Published: February 2021

We presented two clinical cases with clinical manifestations of antiphospholipid syndrome (APS) and ankylosing spondylitis (AS). The peculiarity of these cases is the onset of diseases in childhood, as well as the presence of not only extra-skeletal manifestations, but also complications or manifestations of other pathology. In the first case, it was thrombosis of the superficial veins of the lower limbs with the development of postthrombotic syndrome. In the second case, aortic valve defect, as a result of aortitis with a dilatation of the ascending aorta, which led to aortic valve replacement and its subsequent dysfunction because of thrombosis of the valve prosthesis. The frequency of detection of antiphospholipid antibodies (aPL), APS and thrombosis in AS is discussed. The role of tumor necrosis factor α (TNFα) inhibitors in the induction of aPL synthesis and the development of APS in patients with AS is considered either. Separately, we discussed the role of TNFα inhibitors, which are the main drugs in the treatment of ankylosing spondylitis, in the induction of aPL synthesis and the development of APS. Data on the occurrence of aPL, the reasons for the development of thrombosis in APS and the role of TNFα inhibitors remains incomplete. Perhaps the combination of APS and AS is an underestimated problem, and the information available in the literature does not reflect the real numbers. It is obvious that further research is needed to improve the treatment of patients with AS with thrombosis.

Geoelectrical and geotechnical investigation of foundation failure in and around Oroke high school, Akungba- Akoko, southwestern Nigeria
Authors: O.A Odundun , V.I Fagorite , E.O Rogbitan
Published: February 2021

Engineering structures are designed and constructed with an air of lifelong expectancy. Moreover, building foundation may experience failure due to presence of concealed geologic features such as cavity and shear zones which can lead to subsurface subsidence. Hence, it is imperative, prior to building construction, to investigate the physical properties of foundation soils and determine its suitability for design and construction of building structures. In the light of this, a geoelectric survey, involving three (3) electrical dipole - dipole array and geotechnical analysis methods were carried out around a distressed building at Oroke High School, opposite Adekunle Ajasin University, Akungba Akoko to establish the cause of failure for the structures foundation via delineating the subsurface structural features. The field electrical data were plotted on log â€“log graph sheets and the resulting curves were interpreted qualitatively by visual inspection, and quantitatively via partial curve matching and computer iteration techniques. For the geotechnical analysis, a total of twelve (12) soil samples were taken from different locations of about 30 meters intervals, at the depth of 1.5 meters. The pseudo â€“ section and electrical sections indicate that the subsurface is heterogeneous in geological composition. The 2D dipole- dipole resistivity and pseudo â€“ section delineated zones having resistivity values ranging from 200 to 700ohm meter, and those approaching infinity all within a depth of 0-5 m, the resistivity values of 27 to 139ohm meter suggest the presence of clay. The geoelectric section identified three subsurface geologic layers comprising clay /sandy, clay top soil / sub grade soil, clay / sandy clay and sand weathered layer and the basement (fresh) beneath the failed segment. Additionally, prominent fractures were discovered within some areas on the pseudo-sections. The results of the laboratory tests also included those of natural moisture content, specific gravity, grain size distribution curves, Atterberg limit, compaction test and California Bearing Ratio (CBR). In conclusion, electrical resistivity method was found to be an effective measure or tool in the site characterization. The soil/rock in these zones may require reinforcement in order to enhance its bearing capacity and increase the life span of the engineering foundation.Â Â

The quality of water samples obtained from the health-care center in the Ekiti State University and three other centers around the campus; Ekiti State University Teaching Hospital (EKSUTH), Iworoko-Ekiti health Centre (IHC) and the State Hospital, Ikole-Ekiti (SHI) were investigated by analyzing the total bacterial count using pour plate method; the incidence and antibiotic resistance of Enterococcus faecalis as water quality indicator was enumerated using selective isolation and disk diffusion method respectively. The mean TBC, TCC and TEC of all the water samples ranged from 9.1 x 102 to 17.4 x 103 CFU/ml, 4.1 x 102 to 5.5 x 103 CFU/ml and 0.4 x 102 to 0.4 x 103 CFU/ml respectively. A total of 70 (32.9%) Enterococcus faecalis were recovered from the water samples from Iworoko HC, which showed highest distribution in bore-hole and well water samples while least frequency of E. faecalis (15.7%) was recovered from EKSU HC. However, no incidence of E. faecalis in table water obtained from all the health-care facilities. Just 35% of 20 selected E. faecalis were caseinase producers while 80% of the isolates were biofilm producers. All the isolates were resistant to cefuroxime, cefixime, augmentin and ceftazidine while only 10% of them were resistant to ofloxacin. 58.6% of the isolates showed MAR to eight (8) antibiotics with three different resistotypes while only 1.4% of them showed MAR to four (4) antibiotics with just one resistotype (CRX-CXM-AUG-CAZ). Only E. faecalis15 among the selected isolates possessed two plasmids with molecular weight of 1.415bp and 13.535bp. However, consumption of contaminated water traceable to faecal sources and plasmid mediated of the causative microbes would be discussed.

Published: February 2021

The effects of repeated oral administration of clarithromycin (7.5 mg/Kg B.W., daily for 5 consecutive days) on blood parameters, clinico-chemical parameters and vital organ histology were evaluated in Ross broiler chickens. Twelve clinically healthy birds have been used in a parallel study design, where they have been randomly divided into two groups. The 1st group received a dose of 7.5 mg clarithromycin/Kg as intracrop bolus daily for 5 consecutive days after 6 h fasting; while the 2nd group received iso-saline and was kept as control. Blood samples were collected from all birds via the wing and metatarsal vein punctures on the 5th day for clinico-chemical and haematological examinations; and liver, kidneys and heart were dissected out for histopathological examination. Results revealed that repeated administration of clarithromycin caused significant increases in ALP, AST, ALT, CK, urea and creatinine levels, compared to those of control. Metabolic parameters exhibited significant decrease in albumin with consequent decrease in total protein and decreased albumin/globulin ratio. Lipid parameters remained unchanged, compared to control. Leuckogram revealed that total leuckocytic count was decreased as a result of the decreased number of lymphocytes and mid-sized cells. On the other hand, granulocytes number exhibited significant increase (granulocytosis) together with increased number of platelets (thrombocytosis); while erythrogram remained insignifi-cantly affected. Liver and kidney showed inflammatory cellular infiltrations associated with degenerative changes and haemorrhages. Although heart did not show inflammatory cellular infiltrations, yet breakage in some bundles was noted. These data indicate that although clarithromycin did not cause any clinical serious manifestations on the treated birds, yet laboratory analysis revealed some adverse effects on some organs as liver, kidney and heart as well as alterations in some clinic-chemical and hematological parameters; these findings should be taken in consideration during therapy with clarithromycin.

Background: Psychosocial stress, have been implicated as risk indicators for periodontal disease. Minimal evidence in literature exists to assess the effect of stress reduction therapy (SRT) in the outcome of non-surgical periodontal therapy (NSPT).Objective: Hence, we aimed to explore the possibility of employing SRT in stressed patients as an adjunctive intervention in the management NSPT.Materials and Methods: Sixty male patients divided into Group 1 comprised of 20 unstressed chronic periodontitis patients receiving non-surgical periodontal therapy alone, Group 2a (20 stressed chronic periodontitis patients) received intervention focused on SPT with NSPT and Group 2b (20 stressed chronic periodontitis patients) received only NSPT without SPT. Their stress level was evaluated using a standard questionnaire method and salivary cortisol levels, at baseline and 3 months along with periodontal parameters.Results: There was significant reduction in stress parameters for Group 2a patients. The reduction of total periodontitis affected sites was highest in Group I patients (55.4%), followed by Group 2a patients (53.2%) and Group 2b patients (38%).Conclusion: SRT may result in comparable treatment outcome to unstressed chronic periodontitis patients. This study opens new avenues to investigate the effects of stress management as an adjunctive to conventional NSPT, which should be explored further.Â

Published: February 2021

The effective selection of protein features and the accurate method for predicting protein structural class (PSP) is an important aspect in protein folding, especially for low-similarity sequences. Many promising approaches are proposed to solve this problem, mostly via computational intelligence methods. One of the main aspect of the prediction is the extraction of an excellent representation of a protein sequence. An integrated vector of dimensions 71 was extracted using secondary and hydropathy information in this study Using newly developed strategies for categorizing proteins into their respective main structures classes, which are all-α, all-β, α/β, and α+β. Support Vector Machine (SVM) and Differential Evolution (DE) were combined using the wrapper method to select the top N features based on the level of their respective importance. The classification can be made more accurate by tuning the kernel parameters for the SVM in the training phase. In this study, the mean of the classification rate from using the SVM classifier was used to evaluate the selected subset of features. This study was tested using two low - similarity data sets (D640 and ASTRAL). A comparison between the proposed (SVM + DE) based on DE feature selection approach and (SVM+DE) based on grid search (a traditional method to search for parameters) forms the core of this work. The proposed SVM+DE model is competitive and highly reliable in terms of time and performance accuracy compared with other reported methods in literature.

There is considerable interest in reducing the cost of alloy components that are highly resistant to corrosion. Therefore, low-cost laser energy was used compared to other treatments, where this energy was used to enhance surface resistance of the alloy. In this paper, the advantages of surface treatment using laser energy have demonstrated, in addition, analysis of the effect of the treatment parameters on the material properties. Surface treatment methods for laser materials were classified in thermal processes and thermal chemical processes. The chemical thermal process shows a change in the surface composition of the treated material. The initial state of hydration for cement paste can be identified by analyzing the changes resulting from the intensity of the laser processor. Alumina samples in Ceram proved more soluble areas and became more homogenous and smooth with fewer openings and cracks, especially with energy higher than 10 W CO2 and higher power density than Excimer 6.2 J / cm laser devices. The optimum power of the laser used to remove the material is 40-200 W / cm2.Â

Authors: Vogiatzis Tzanetis , Tsalkatidis Themistoklis , Avdelas Aris
Published: February 2021

In recent years, hybrid steel-timber structures are seeing an increasing use in modern building construction at a competitive price. Cross-laminated timber (CLT) is a prefabricated multi-layer engineered panel wood product, manufactured by gluing layers of solid-sawn lumber at perpendicular angles. Their orientation results in excellent structural rigidity in both orthogonal directions. CLT construction materials are used not only for flooring systems and roof assemblies, but CLT infill shear walls are also gaining a lot of interest as a promising alternative for sustainable primary lateral load resistance systems. This paper extends the current research background on hybrid steel-timber structures. To achieve that, this work is conducted in such way as to explore the potentiality of incorporating CLT infill shear walls within steel framed structures with semi-rigid connections (STSW). In particular, a three-dimensional finite element model using the general-purpose finite ele-ment program ANSYS is generated herein to study the mechanical behaviour of a single-bay, two storey STSW system with semi-rigid connections. Analytical results show that the presence of CLT infill shear walls can significantly improve the performance of moment-resisting frame systems, for multi-storey buildings. Moreover, it is observed from the extended parametrical study that the STSW systems show better performance when an appropriate plastic moment ratio index is defined.

Published: February 2021

One of the most relevant problems in transport engineering is the planning of multimodal movements where it is necessary to define the logistics network. To analyze the logistics of a foreign trade operator in Colombia, a mathematical model has been designed for the choice of ports, considering multimodal transport and the state of the art. Initially, a multimodal network was built considering modes of maritime, river, rail and road transport, taking advantage of the main river of Colombia (Magdalena river) and the railway infrastructure. Port operating costs, transshipment, port fees, sea freight, operational and variable costs were included in the analysis. It was found that the most suitable ports in Colombia for export are Cartagena and Buenaventura, with the current infrastructure and demand. It has been found that multimodal arcs are more used than those with a single mode, in addition to exports to Ecuador being made by Buenaventura, while to America and Europe is Cartagena. Additionally, there is sensitivity in the choice of ports concerning the level of prices of road transport since in the Colombian context it is vital to change transfers due to the lack of connectivity between modes such as rail and river.Â Â Â
Introduction to random division multiple access (RDMA) applicable for mobile satellite communications
Authors: Stojce Ilcev Dimov
Published: February 2021

This paper describes in particular Random Division Multiple Access (RDMA) applicable in Mobile Satellite Communications (MSC). In satellite communication systems, as a rule, especially in Mobile Satellite Communications (MSC) many users are active at the same time. The problem of simultaneous communications between many single or multipoint mobile satellite users, however, can be solved by using Multiple Access (MA) technique. Since the resources of the systems such as the transmitting power and the bandwidth are limited, it is advisable to use the channels with complete charge and to create a different MA to the channel. This generates a problem of summation and separation of signals in the transmission and reception parts, respectively. Deciding this problem consists in the development of orthogonal channels of transmission in order to divide signals from various users unambiguously on the reception part.Â Â Â
A clustering algorithm for solving the vehicle routing assignment problem in polynomial time
Authors: W. Rizkallah L. , F. Ahmed M. , M. Darwish N.
Published: February 2021

The Vehicle Routing Problem (VRP) consists of a group of customers that needs to be served. Each customer has a certain demand of goods. A central depot having a fleet of vehicles is responsible for supplying the customers with their demands. The problem is composed of two sub-problems: The first sub-problem is an assignment problem where both the vehicles that will be used as well as the customers assigned to each vehicle are determined. The second sub-problem is the routing problem in which for each vehicle having a number of cus-tomers assigned to it, the order of visits of the customers is determined. Optimal number of vehicles as well as optimal total distance should be achieved. In this paper, an approach for solving the first sub-problem, the assignment problem, is presented. In the approach, a clustering algorithm is proposed for finding the optimal number of vehicles by grouping the customers into clusters where each cluster is visited by one vehicle. This work presents a polynomial time clustering algorithm for finding the optimal number of clusters. Also, a solution to the assignment problem is provided. The proposed approach was evaluated using Solomonâ€™s C1 benchmarks where it reached optimal number of clusters for all the benchmarks in this category. The proposed approach succeeds in solving the assignment problem in VRP achieving a solving time that surpasses the state-of-the-art approaches provided in the literature. It also provides a means of working with varying num-ber of customers without major increase in solving time.Â Â

The digital preservation has historical implications, it has a direct effect on the cultural heritage, because, without information (digital or not) that is guarded, there is no inheritance or culture, but without technology that allows the preservation or recovery of such information, neither would it be, Thus, the research question is posed as: What technical and legal characteristics are necessary to have an adaptive digital preservation model based on aspects of digital object management and organizational infrastructure, to ensure accessibility of information in the long term in public institutions of Ecuador ?, determining through an evaluation of NESTOR trust repositories and Ecuadorian legislation, that it is necessary to create an adaptive digital Preservation model.Â Â Â
Deep learning-based car seatbelt classifier resilient to weather conditions
Authors: Hosameldeen Osama
Published: February 2021

Deep Learning is a very promising field in image classification. It leads to the automation of many real-world problems. Currently, Car seatbelt violation detection is done manually or partial manual. In this paper, an approach is proposed to make the seat belt detection process fully automated. To make the detection more accurate, sensors are set to detect the weather condition. When spe-cific weather condition is detected, the corresponding pre-trained model is assigned the detection task. In other words, a research is conducted to check the possibility of dividing the big-sized deep-learning model - that can classify car seatbelt, into sub-models each one can detect specific weather condition. Accordingly, a single specialized model is used for each weather condition, Deep convolutional neural network (CNN) model AlexNet is used in the detection/classification process. The proposed system is sensor based AlexNet (S-AlexNet). Results support our hypothesis that â€œUsing single model for each weather condition is better than gen-eral model that support all weather conditionsâ€. On average, previous approaches that trained single model for all weather condi-tions have accuracy less than 90%. The proposed S-AlexNet approach successfully reaches 90+% accuracy.Â Â

This research was performed so as to appraise strength and properties of lateritic soils enriched with hydrated lime and bitumen as construction materials. Soil samplings S1, S2, S3, S4, and S5 was collected from Dualization of Sheda - Abaji, Abuja, F.C.T, Ni-geria and augment with 0, 3, 6, 9, and 12% of hydrated lime and bitumen. Laboratory tests like Consistency (Atterberg limit), California Bearing Ratio (C.B.R), compaction and sieve scrutiny were done on the soil sampling. The study exposed that construc-tive effects were gotten via the addition of hydrated lime and bitumen in order to augment the strength of weak soils. All the 5 samplings have C.B.R values of 48.0% with hydrated lime as additives, whereas bitumen additive is 40.60%. Introduction of addi-tives enriched the soil samplings from weak materials to an excellent base material with C.B.R values above 40%. Hence, aug-mentation of lateritic soil samplings from the studied locality could be perform efficiently by using lime.Â Â

This work presents ideally the behavioral characteristics of induction motor (IM) when subjected to different loading conditions. The task is achieved via mathematical modeling of the process using the Simulink tool of the Matlab. Dynamic model is generally used to study the steady state and transient behavior of induction motor. Here, Clarke and Parkâ€™s transformation of stator and rotor parameters on the synchronously rotating reference frame is applied to the developed mathematical model of the induction motor. First, the differential equations of voltages, currents and flux linkages between the stationary stator and rotating rotor are developed, followed by the mechanical equation of torque and speed. Thereafter the mathematical model developed with the help of the software is generally used to study the variation in parameters value on the dynamic performance of the induction motor as variable load is driven. The obtained simulated results apart from the exhibited performances still suggests that the synchronously rotating reference frame theory is actually a shrewd process to validate the dynamic behavior of the induction motor.Â Â Â

The Northern Gaza Emergency Sewage Treatment (NGEST) is addressed as a promising water management intervention strategy to maintain the sustainability of groundwater aquifer in the Gaza Strip. This study assesses the current operational status of the north-ern Gaza wastewater infiltration basins located at NGEST project. In situ diagnostic assessment was performed at two spots (A) and (B) located inside the basin (3). The results of sieve analysis and bulk density indicate that the soil at the spot (B) is finer than of spot (A) where the contents of the fine material and bulk densities were 13% and 1544 kg/m3 at the spot (A) and 23.7% and 1544 kg/m3 at the spot (B). In terms of the infiltration capacity, the nature of soil at the spot (A) exhibits better initial and saturated infil-tration rate in comparison to the soil at the spot (B), where the initial and saturated infiltration rates were 2.88 and 0.43 for spot (A) and 0.29 and 1.73 meters per day for spot (B), respectively. Thus, the diagnostic assessment for the northern Gaza wastewater infil-tration basins indicates that the soil classification is silty sand and the infiltration rates range between about 3 and 0.3 meters per day.Â Â

Fibers and bacterial additives in concrete have achieved significant success as a construction material. This paper presents the field of concrete self-repairing by introducing both Bacillus subtilis bacteria and polyethylene fiber as a dual-components. The main research goal is to reveal the principles of concrete self-repairing. At first, the research investigates the fiber-reinforced-concrete behavior, the concrete self-repairing process with the Bacillus subtilis bacteria for forming bacterial-concrete. And then, the study highlights the damage-repairing numerical simulation of fiber-reinforced-bacterial-concrete. The research shows the bacterial-concrete benefits to durability and mechanical properties besides to the polyethylene fiber assistance to enhance post-cracking tensile resistance and the pre-peak elastic modulus of concrete. The novelty of the fiber-reinforced-bacterial-concrete is the matrix combined improvement of both basic material properties and the post-cracking deflection capacity.Â Â

Published: February 2021

The ever-growing population and globalization have resulted into an increase in demand for power. Additionally, ecological concerns like an unnatural weather change have constrained us to locate new and different substitutes to the current conventional sources of energy. To provide a solution to this crisis of energy in a way that is environment friendly, we have focused our attention towards making renewable energy resources as an alternative to currently employed sources of power. This paper contains extensive study on different Distributed Generation (DG) sources, comparing their merits and demerits also comprising of the impact when added to an already existing AC power grid. Accordingly, the planning methodologies have been discussed which will help us in determining which type of DG suits best to our requirement. This paper also contains the review of optimal placement techniques and sizing methodologies for DG system in grid networks, which are together known as Hybrid Energy Systems (HES).Â

Design and implementation of accurate frequency estimator depend on deep learning
Authors: Saber Mohamed , M.El-Kenawy El-sayed
Published: February 2021

An Accurate, efficient, and stable system to estimate the unknown input frequency of a sinusoidal signal is presented. The proposed design solves the main drawback of the existing phase-based estimator which called a derivative estimator depend on deep learning. These limitations are the inability to estimate low frequencies and the large estimation errors for the frequencies near the Nyquist rate. A Brief mathematical analysis in discrete-time of the proposed system is presented. Proposed estimator performance when the input is a single sinusoid, multiple sinusoids in the presence of additive white Gaussian noise (AWGN) are provided. The accuracy of the proposed esti-mator is the result of dividing the dynamic range of estimation to three regions (low frequencies, middle frequencies, high frequencies) and specify a different formula to calculate the estimated frequency in each region. The boundaries of each region are determined by using a Grey wolf optimizer (GWO) which training bidirectional recurrent neural networks (BRNN) to select the best weights for the estimated frequency. The simulation results ensure the accuracy and validity of the proposed estimator compared to the traditional one. The hardware implementation of enhanced estimator using field-programmable gate array (FPGA), consumed 265 mW, and worked at 375 MHz.Â Â
