The introduction of robot-assisted surgery into the operating room has revolutionized the medical field.
These systems not only have the advantages of traditional minimally invasive surgery (MIS), such as reduced patient
trauma and recovery time, lower morbidity, and lower health care costs, but they also eliminate surgeon tremor,
reduce the effects of surgeon fatigue, and incorporate the ability to perform remote surgical procedures. However,
current robotic surgical systems, such as the Da Vinci™ Surgical System, lack the capability of providing force
feedback to the surgeon that is present in conventional surgery. Therefore, this lack of force feedback presents
excellent developmental opportunities for surgeons and engineers to create novel surgical tools and methods to
incorporate force feedback capabilities into these robotic surgical systems. The goal of this research is to restore force
feedback capability to the surgeon in robot-assisted surgery through a haptic interaction experience involving force
feedback from the surgical site using our novel teleoperation platform. This project will summarize our research
including: 1)The Laparoscopic tool will be mounted over robotic arm.2)The Laparoscopic grasper can be integrated
with force feedback system and tactile system.3)Incorporation of master slave technique in prototype model.4)The
sensors will be used to transmit force data to slave controller and then transmitted wirelessly to master controller
which then controlled by servo motor(force feedback device.5)Opening and closing process of Laparoscopic grasper is controlled by servo motor.
Microsurgery involves highly precise surgery performed under a microscope. It is used to reconnect small blood vessels and nerves after injuries and reconstructive procedures. Extensive training is required for surgeons to master the delicate techniques of microsurgery. Key aspects include reattaching amputated body parts, transplanting tissue flaps between areas, and repairing nerves and blood vessels down to a microscopic level. Microsurgery relies on specialized tools and sutures, as well as operating microscopes, to enable surgeons to visualize and manipulate tiny anatomical structures.

Piezosurgery is a surgical technique that uses ultrasonic vibrations to selectively cut bone with minimal damage to soft tissues. It was developed in the late 1980s and uses a piezoelectric effect where crystals produce electrical current under pressure. Key advantages are precise cuts with good visibility and less soft tissue trauma compared to rotating burs. Applications include dental extractions, bone grafting, sinus lifts and implantology. While it reduces complications, limitations are longer operating times and higher costs compared to traditional techniques.
This document describes a bone strain measurement system using an FPGA. The system aims to measure bone strain to analyze bone characteristics and how structural properties change with mechanical loads and biological factors. Strain gauges attached to bone samples convert strain into voltage signals, which are transmitted for processing. The FPGA implementation reduces design time and cost while consuming low power. Comparison of patient bone strain details to a database could aid diagnosis of bone diseases like osteoporosis.
This study compared the skeletal and dental transverse effects of surgically assisted rapid maxillary expansion (SARME) using Haas versus Hyrax expanders in 38 patients aged 18-39 years. Measurements of maxillary width, upper intermolar width, and molar inclination were made before, immediately after, and 4 months after SARME. Both groups showed significant increases in maxillary width and intermolar width immediately after SARME, with decreases at 4 months but remaining significantly wider than before. The amount of maxillary widening was about 70% of the intermolar width increase. Clinically, the transverse effects were similar between the Haas and Hyrax groups.
This document summarizes a study of 110 patients who underwent distal femur resection and endoprosthetic reconstruction between 1980-1998. The majority had malignant bone tumors. Reconstruction was performed with modular, custom-made, or expandable prostheses. At minimum 2-year follow up, function was good or excellent in 85% of patients. Complications included deep infection in 5%, aseptic loosening in 5%, and prosthetic failure in 5%. The limb salvage rate was 96%. Distal femur endoprosthetic reconstruction provided good function and local tumor control in most patients.
Vitamin E capsules can effectively be used as fiducial markers for image-guided neurosurgery, providing accurate registration while significantly reducing costs compared to proprietary fiducials. The use of Vitamin E capsules for registration resulted in a mean overall accuracy of 1.84 mm, compared to 2.41 mm for regular fiducials. Image guidance improves the safety, accuracy, and visualization for trans-sphenoidal pituitary surgeries compared to fluoroscopy alone.
Design Evaluation and Development of Lumbar Cageijtsrd
Lumbar spinal fusion is advance method of surgery to permanently join or fuse two or more vertebrae in the human spine in order to eliminate the relative motion between them. It is currently considered as the most successful surgery in the patients with spinal deformity and degenerative spondylolisthesis. Its success critically depends on the geometric design of the interbody cages and the material properties of the material used. The main objective of this work is to design analyse and develop a 3D model of the intervertebrae disc for human lumbar spine based on anatomical reverse engineering techniques ARE techniques such as magnetic resonance imaging MRI scan. For this purpose, the sizes of L4 L5 which are the largest vertebrae of the human spine, were observed and modeled accordingly by using CREO with standard dimensions. The prototype was made with PLA plastic using an FDM 3D printer. The analytical tests were carried on ANSYS by applying various complex motions on the intervertebrae disc surface and the stress distributions were compared for the optimization of lumbar cage design. The compression force was applied on the prototype and observed till failure. Results obtained were compared for static position of the lumbar cage, of both analytical and physical outcomes. T.

IROS 2009 - Three-layer Control for Active Wrists in Robotized Laparoscopic S...Robótica Médica UMA
This paper is focused on the motion control problem for a laparoscopic surgery robot assistant with an actuated wrist. These assistants may apply non-desired efforts to the patient abdomen. Therefore, this article proposes a control methodology based on three feedback levels, which have been defined as layers. These layers control different aspects of the endoscope movement. A low level assures the dynamic of the robot assistant is performed accordingly. The mid level emulates a passive wrist behavior to avoid any efforts over the abdomen. An external high level deals with the global movement planning. This architecture also makes easier to analyze the stability of the whole system. Finally, a real in-vitro experiment has been implemented with an industrial robot in order to contrast the validity of this article procedure.

Secure communication for mobile Adhoc network using (LPIT) Lagrange polynomia...AM Publications
Mobile adhoc network is collection of autonomous nodes that are frequently moving without the centralized
control. Mobile adhoc networks are multi hop wireless networks without fixed infrastructure. Node frequently change
topology, due to this type of behavior transformation of information from one node to another node is more
complicated task. Decentralized nature of mobile adhoc network is more vulnerable to attack like denial of service
(DOS) which consumes more bandwidth and resources. Security is major concern in adhoc network, so in this paper,
we propose a new algorithm based on Lagrange polynomial and Laplace transform and inverse Laplace transform to
enhance secure communication for MANET. This proposed algorithm provides security for transmission of
information among node.

Autonomous Camera Movement for Robotic-Assisted Surgery: A SurveyIJAEMSJORNAL
In the past decade, Robotic-Assisted Surgery (RAS) has become a widely accepted technique as an alternative to traditional open surgery procedures. The best robotic assistant system should combine both human and robot capabilities under the human control. As a matter of fact robot should collaborate with surgeons in a natural and autonomous way, thus requiring less of the surgeons’ attention. In this survey, we provide a comprehensive and structured review of the robotic-assisted surgery and autonomous camera movement for RAS operation. We also discuss several topics, including but not limited to task and gesture recognition, that are closely related to robotic-assisted surgery automation and illustrate several successful applications in various real-world application domains. We hope that this paper will provide a more thorough understanding of the recent advances in camera automation in RSA and offer some future research directions.
Robotic colorectal surgery technique, advantages, disadvantages and its impac...Apollo Hospitals
The use of robotics in colorectal surgery is gaining momentum of late. Technical advances, such as three-dimensional imaging, a stable camera platform, excellent ergonomics, tremor elimination, ambidextrous capability, motion scaling and instruments with multiple degrees of freedom, have helped many surgeons adapt to it easily. There is a shorter learning curve compared to the standard laparoscopic surgery. This article helps to give an outline as to how robotic colorectal surgery can go a long way in the future of colorectal surgery.
This document summarizes a research paper about a MEMS sensor-controlled haptic forefinger robotic aid. The proposed system uses a MEMS sensor placed on the forefinger to detect the direction of finger movement. This direction information is transmitted via RF to a receiving microcontroller unit that commands a robot to move in the corresponding direction. The design aims to provide a low-cost robotic aid for physically challenged individuals by allowing simple control of a robot through natural forefinger movements. Experimental results validating the forefinger-based directional control of the robot are presented.
This document provides an overview of how virtual reality is being applied in various areas of medicine, with a focus on surgery, neurosurgery, and mental and physical rehabilitation. It discusses how VR is used for surgical planning and simulation, particularly for minimally invasive endoscopic surgery. VR training simulators are also described as a way to practice new procedures safely. The document outlines some of the technical challenges in making VR simulations realistic and the transfer of skills from VR to real-world surgery. Pre-operative planning systems that use actual patient data are distinguished from training simulations. Telemedicine and collaborative applications are also mentioned.
This document summarizes research on artificial intelligence arms and prosthetic hands. It discusses how prosthetic limbs have advanced with developments in information technology, allowing them to more easily connect to a person's brain or muscles for movement. However, current prosthetic hands remain inferior to natural hands. The document also reviews the history of prosthetic hand development from pneumatic to myoelectric systems. Despite advances, rejection rates of upper limb prosthetics remain high. Future improvements may come from advances in areas like materials, battery life, control systems, surgical techniques, and 3D printing.
The document discusses integrating medical robots for brain surgical applications. It describes several robotic systems that are being used or developed for neurosurgery to improve precision and reduce human errors. These include supervised robotic systems that complete pre-planned tasks autonomously as well as telesurgical systems that allow surgeons to remotely control robots from other locations. Robotic systems are helping to perform minimally invasive brain surgeries and procedures with improved accuracy.
This document summarizes two cases of laparoscopic partial nephrectomy performed using a novel articulating laparoscopic needle driver called the FlexDex. The FlexDex aims to provide the seven degrees of motion of robotic instruments while maintaining the advantages of traditional laparoscopy. The cases demonstrated the feasibility of using the FlexDex for renorrhaphy. Compared to the first case, the second case benefited from improved port placement and had shorter clamping time and less blood loss, showing the surgeon's learning with the new instrument. The FlexDex may help bridge the gap between laparoscopy and robotics by providing a more intuitive laparoscopic alternative.

This document summarizes the history and development of telesurgery and surgical robotics. It discusses how early Greek surgeons began using basic surgical tools to separate the surgeon's hands from the patient. The development of laparoscopic surgery in the 20th century further reduced surgical trauma by moving the surgeon's hands outside of the body. Surgical robotics in the 1980s allowed procedures to be performed remotely using telemanipulators with a master console separated from slave robotic arms. A key milestone was the first transatlantic telesurgical procedure in 2001. While challenges remain, telesurgery holds promise to improve access to surgical expertise worldwide.

This document discusses the history and applications of robotic surgery in ENT. It begins with the origins of robotics in the 1920s and the emergence of surgical robotics from advances in other fields. The da Vinci surgical system is currently the most widely used system, allowing 7 degrees of freedom of motion and 3D visualization. Initial ENT applications included transoral surgery and thyroid procedures. Transoral robotic surgery (TORS) allows improved access and resection for tumors of the tonsil, base of tongue, and larynx. Robotic thyroid surgery reduces incision sizes. Future areas may include sinus and skull base procedures as technology advances.
Most surgeons and patients agree that minimally invasive surgery is preferable to open surgery, as it results in less post-operative pain, shorter hospital stays, and easier recovery. Both laparoscopic and robotic surgery are types of minimally invasive surgery. Laparoscopic surgery involves making several small incisions to insert small tools including a video camera, while robotic surgery uses a computer-controlled robot to manipulate instruments with greater precision via a 3D high-definition video feed. Robotic surgery allows for a greater range of motion than laparoscopic surgery and enables surgeons to access more difficult to reach areas. Both result in shorter recovery times compared to traditional open surgery.
A new tactile probe called Elastirob has been designed and fabricated to measure the elasticity of soft biological tissues. Elastirob consists of a tactile probe, data processing system, and tactile display interface. The tactile probe uses a force sensing resistor sensor attached to a rigid bar that can apply step-wise compression via a stepper motor. The data processing system collects and prepares the sensor data and communicates with the tactile display and stepper motor. The tactile display, called TacPlay, allows users to view and analyze the stress-strain curves generated during testing to calculate elastic modulus. Initial testing of Elastirob showed it could successfully measure the elasticity of tissue samples and compare
Early experience with the da vinci® surgicalTariq Mohammed
This document summarizes the author's early experience using the da Vinci surgical robot for gynecological surgeries at King Abdulaziz University Hospital between 2008-2010. The author performed 35 surgeries on patients using the robot, with an average docking time of 7 minutes and hospital stay of 3 days. While there was a 6.5% conversion rate to open surgery for early cases, complications occurred in 14% of patients but were not directly related to the robotic system. The author concludes that with proper training, technical difficulties can be limited when using the robot for gynecological procedures.
The document discusses the history and development of robotic surgery. It describes how the first robotic surgery device, the PUMA 560, was used in 1985 for brain biopsies. Later systems like PROBOT and ROBODOC were developed in the late 1980s and early 1990s. The da Vinci surgical system was approved by the FDA in 2000 and is now commonly used for procedures like prostatectomies and cardiac/gynecological surgeries. The da Vinci allows surgeons to operate remotely through small incisions while magnifying their hand movements. Robotic surgery provides benefits like shorter recovery times but drawbacks include the high costs of equipment and training. New innovations continue to advance the field.
The document discusses the advancement of robotic surgery. It describes how the first generation of surgical robots are being installed in operating rooms around the world to assist surgeons through remote control and voice activation. The robots allow for unprecedented precision in minimally invasive procedures. The ultimate goal is to design a robot that can perform closed-chest, beating-heart surgery autonomously. Robotic surgery provides benefits to both patients through reduced pain and scarring and to surgeons and hospitals.
Robotic surgery uses robotic systems to assist surgeons with complex procedures. A robotic system typically includes a surgeon console for control of robotic arms with surgical instruments, an endoscope for vision, and a surgical cart. Robotic systems allow 7 degrees of freedom of instrument movement compared to 4 for laparoscopy, improving dexterity. The da Vinci system is most commonly used and has been applied to procedures in general surgery, urology, gynecology and others. Robotic surgery provides benefits like 3D high-definition vision, tremor filtering and motion scaling but lacks haptic feedback. It has longer procedure times but may improve precision and surgical outcomes for some procedures like prostatectomy compared to open or laparoscopic approaches.
Robotic surgery originated in the 1980s with early conceptions of telepresence surgery using robotic arms controlled by surgeons. The first robot used for surgery was the Puma 560 for neurosurgical biopsies. The Da Vinci system, introduced by Intuitive Surgical, performed the first telesurgical laparoscopic cholecystectomy in 1997. The Da Vinci system allows surgeons to perform minimally invasive procedures with improved 3D visualization, dexterity, precision, and ergonomics compared to traditional laparoscopy. Robotic surgery has been used for a wide variety of procedures in fields such as general surgery, urology, gynecology and cardiac surgery.
1. Robotic total knee arthroplasty (TKA) uses preoperative imaging and intraoperative robotics to improve the accuracy of implant positioning and soft tissue balancing compared to conventional jig-based TKA.
2. Earlier robotic systems were associated with technical complications in up to 30% of cases, but complication rates with newer systems, such as Mako and Navio, appear to be low.
3. Robotic TKA systems can be classified as passive, active, interactive, or teleoperated based on their level of autonomy and interaction with the surgeon. The most widely used interactive systems currently are Mako, Navio, Rosa, and Cori.
Telemedicine is a new and hopeful application in the field of medical science. Medical consulting and remote medical procedures or examinations became more successful with the development of interactive audiovisual systems and distant movable robotic platforms. Tele-presence requires real time video communication. Fixed mounting of video device on mobile robotic platform limits the video projection at positive vision angle, thus restricting the remote doctor in obtaining the better and correct visual information of the patient. To avoid the problem, this paper presents a flexible robotic arm with vision system. A thirteen degree of freedom robotic arm with extending and retracting quality enables the remote doctor to clear the attached video device on robotic arm to object area on patient. The rising necessity for robotic applications in dynamic unstructured environments is inspiring the need for dexterous end-effectors which have the wide variety of tasks and objects encountered in these environments. The human hand is a very complex grasping tool that can handle objects of different sizes and shapes. This hand gripper is the wide working space compared with its physical dimensions and the capability to deal with objects in working environment conditions. This capability is achieved by using force/torque sensor and by properly controlling and coordinating the gripper and the carrying arm Note that with this control structure, it is also very simple to connect the arm/gripper system using Internet to other computational resources or robotic devices, for example to emulate tele-operation tasks.

PEDESTRIAN DETECTION IN LOW RESOLUTION VIDEOS USING A MULTI-FRAME HOG-BASED D...AM Publications
Detecting pedestrians in low resolution videos is a challenging task, due to the small size of pedestrians in the images and the limited information. In practical outdoor surveillance scenarios the pedestrian size is usually small. Existing state-of-the-art pedestrian detection methods that use histogram of oriented gradient (HOG) features have poor performance in this problem domain. To compensate for the lack of information in a single frame, we propose a novel detection method that recognizes pedestrians in a short sequence of frames. Namely, we take the single-frame HOG-based detector and extend it to multiple frames. Our detector is applied to regions containing potential moving objects. In the case of video taken from a moving camera on an aerial platform, video stabilization is first performed to register the frames. A classifier is then applied to features extracted from spatio-temporal volumes surrounding the potential moving objects. On challenging stationary and aerial video datasets, our detection accuracy outperforms several state-of-the-art algorithms.

EFFECT OF SILICON - RUBBER (SR) SHEETS AS AN ALTERNATIVE FILTER ON HIGH AND L...AM Publications
A digital radiography delivers a radiation dose to patients; therefore it poses potential risk to the patients. One effort to reduce dose is carried out using a radiation filter, e.g. Silicone Rubber (SR) sheet. The purpose of this research was to determine the impact of the SR sheet on the high contrast objects (HCO) and the low contrast objects (LCO). The dose reduction was determined from attenuation x-rays before and after using the SR sheet. Assessment of HCO and LCO was observed from CDR TOR phantom at tube voltage of 48 kVp and tube current of 8 mAs. The physical parameter to assess image quality was the Signal to Noise Ratio (SNR) value in LCO. The maximum x-ray attenuation using the SR sheet is 48.82%. The visibility of the HCO remains the same, namely 16 objects; however the LCO slighly decreases from 14 objects to 13 objects after using the SR sheet. The SNR value decreases with an average value of 15.17%.Therefore, the SR sheet as a alternative filter has no effect on the HCO and has realtively little effect on the LCO. Thus, the SR sheet potentially is used for radiation protection in patients, especially on examinations that do not require low contrast resolution.

Surveillance refers to the task of observing a scene, often for lengthy periods in search of particular objects or particular behaviour. This task has many applications, foremost among them is security (monitoring for undesirable behaviour such as theft or vandalism), but increasing numbers of others in areas such as agriculture also exist. Historically, closed circuit TV (CCTV) surveillance has been mundane and labour Intensive, involving personnel scanning multiple screens, but the advent of reasonably priced fast hardware means that automatic surveillance is becoming a realistic task to attempt in real time. Several attempts at this are underway.

ANALYSIS ON LOAD BALANCING ALGORITHMS IMPLEMENTATION ON CLOUD COMPUTING ENVIR...AM Publications
Cloud computing means storing and accessing data and programs over the Internet instead of your computer's hard drive. The cloud is just a metaphor for the Internet. The elements involved in cloud computing are clients, data center and distributed server. One of the main problems in cloud computing is load balancing. Balancing the load means to distribute the workload among several nodes evenly so that no single node will be overloaded. Load can be of any type that is it can be CPU load, memory capacity or network load. In this paper we presented an architecture of load balancing and algorithm which will further improve the load balancing problem by minimizing the response time. In this paper, we have proposed the enhanced version of existing regulated load balancing approach for cloud computing by comping the Randomization and greedy load balancing algorithm. To check the performance of proposed approach, we have used the cloud analyst simulator (Cloud Analyst). Through simulation analysis, it has been found that proposed improved version of regulated load balancing approach has shown better performance in terms of cost, response time and data processing time.

A high-Speed Communication System is based on the Design of a Bi-NoC Router, ...DharmaBanothu
The Network on Chip (NoC) has emerged as an effective
solution for intercommunication infrastructure within System on
Chip (SoC) designs, overcoming the limitations of traditional
methods that face significant bottlenecks. However, the complexity
of NoC design presents numerous challenges related to
performance metrics such as scalability, latency, power
consumption, and signal integrity. This project addresses the
issues within the router's memory unit and proposes an enhanced
memory structure. To achieve efficient data transfer, FIFO buffers
are implemented in distributed RAM and virtual channels for
FPGA-based NoC. The project introduces advanced FIFO-based
memory units within the NoC router, assessing their performance
in a Bi-directional NoC (Bi-NoC) configuration. The primary
objective is to reduce the router's workload while enhancing the
FIFO internal structure. To further improve data transfer speed,
a Bi-NoC with a self-configurable intercommunication channel is
suggested. Simulation and synthesis results demonstrate
guaranteed throughput, predictable latency, and equitable
network access, showing significant improvement over previous
designs

Prediction of Electrical Energy Efficiency Using Information on Consumer's Ac...PriyankaKilaniya
Energy efficiency has been important since the latter part of the last century. The main object of this survey is to determine the energy efficiency knowledge among consumers. Two separate districts in Bangladesh are selected to conduct the survey on households and showrooms about the energy and seller also. The survey uses the data to find some regression equations from which it is easy to predict energy efficiency knowledge. The data is analyzed and calculated based on five important criteria. The initial target was to find some factors that help predict a person's energy efficiency knowledge. From the survey, it is found that the energy efficiency awareness among the people of our country is very low. Relationships between household energy use behaviors are estimated using a unique dataset of about 40 households and 20 showrooms in Bangladesh's Chapainawabganj and Bagerhat districts. Knowledge of energy consumption and energy efficiency technology options is found to be associated with household use of energy conservation practices. Household characteristics also influence household energy use behavior. Younger household cohorts are more likely to adopt energy-efficient technologies and energy conservation practices and place primary importance on energy saving for environmental reasons. Education also influences attitudes toward energy conservation in Bangladesh. Low-education households indicate they primarily save electricity for the environment while high-education households indicate they are motivated by environmental concerns.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODELijaia
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.
