Because of the Asian population's comparatively smaller structure and stature, many surgeons claim that imported implants may not be well fitted for Asian origin patients, mainly based on Western morphometry. It is very likely that an overweight section will be used in many Asian centres in most operations, resulting in low results of the procedure of the implant. For joint substitution of distal femur, careful positioning of fitted implants as well as balancing of underlying soft tissues is important. It is also important to use incredibly complex surgical procedures. To retain its usual functional motion spectrum, use of a suitable femoral part dimension is necessary. Furthermore, owing to a discrepancy between the size of the prosthesis and the bone, there could be a host of serious issues. Objectives: To calculate the anthropom...

We cannot predict nativity of the image without forensic analysis. Tampering with the image is common nowadays with a lot of online and offline tools. To hide an object in an image, regions of the same image are copied and pasted on that object, and this is known as copy-move forgery. In this paper, we have introduced a technique to detect such type of forgery, known as CMFD. In this technique, the image is pre-processed by converting RGB into YCbCr and then Y channel is decomposed into four components of translation-invariant stationary wavelet transform (SWT). Its LL (approximation) component is then divided into 8 × 8 blocks. Further, from each block, we have taken six mean features which are calculated by dividing each block into four squares and two triangular blocks and put them into feature vector with block location. After sorting these feature vectors into lexicographical order, we get the location of forged regions.

This project aims to create an interactive Android application. Users can find different types of workers that includes plumber, electrician, carpenter, packers and movers, home cleaners on OneTouch application. Due to lack of geographical knowledge, people need more time to explore such new locality. In such situations, an application which can help people to get home services quickly proves to be a useful and important tool. Our aim is to design an application, to help needy people to find home service worker very easily in a cost efficient manner. It will provide list of worker for a particular selected category and user will be able to select worker by their choice. Workers available in the nearby location will be given priority first and if no worker is available then radius of finding worker will be increased gradually. Worker’s location, distance, and time required to reach home will be calculated and visible to the user. The cost is calculated dynamically by the app after considering different parameters and final cost is displayed to the user. Dynamic pricing is applied in order to overcome less salary problems of the workers.

The proposed copy-move forgery detection (CMFD) technique relies on DCT and ORB feature extraction and distance-based clustering approach. Extracted DCT features are matched based on Euclidean distance. Extracted key-points using ORB are matched using k-NN procedure based on Hamming distances. To improve accuracy, false matches are removed with the help of a distance-based clustering technique. The proposed technique is applied for testing on CoMoFoD small dataset. Results on experimentation showcase that the technique is efficient in detecting copy-move forged regions and also robust towards brightness and contrast change, noise addition, geometric transformations like scaling and rotation and several forgeries. The proposed technique is compared with two state-of-the art techniques.

The crack considered is transverse crack which open in nature. Due to the presence of crack, the total flexibility matrix is established by adding local additional flexibility matrix to the flexibility matrix of the corresponding intact beam element. The results obtained from experimental are checked for accuracy with the present analysis by plotting non dimensional frequencies for first three modes as function of crack depth ratios for different locations of cracks. Components with varying cross-sections are most common in buildings and bridges as well as in machine parts. The stability of such structural members subjected to compressive forces is a topic of considerable scientific and practical interest. Tapered and stepped columns are very much useful in structural engineering because of their reduced weig...

Copy-move forgery (CMF) is one of the most common image tampering techniques being used. There are many post-processing techniques applied on forged images such as scaling, blurring, JPEG compression and rotation to hide forgery traces. Single image might contain multiple forged regions. In this paper, we have proposed a hybrid method involving DCT (Discrete cosine Transform) and BRISK (Binary Robust Invariant Scalable Keypoints) features, for copy-move forgery detection. DCT is a feature set that would provide invariance to blurring, while BRISK would provide invariance to rotation and scaling. Features are extracted using DCT and BRISK keypoints and descriptors. For matching BRISK descriptors FLANN matcher is used, and for removing the false matches Euclidean distance-based clustering technique is used. The experimental result shows that our method is not only robust to blurring but also robust to transformations like rotation and scaling. It is also able to detect multiple forged regions. The method is tested on CoMoFoD dataset. Results of the proposed work are also compared with two standard approaches mentioned in experiment and result section.

These mobilities such as gait depends on a complex interplay of major parts of the nervous, musculoskeletal and cardiorespiratory systems. Every individuals gait pattern is influenced by age, personality, mood, sociocultural factors and predominantly the persons health condition. In order to understand the health condition of an elderly person, analysis of gait patterns became an important aspect. Gait parameters such as cadence, step length, step duration etc. analyzed out of gait patterns proved as an important factor in estimation of the healthy daily living. For this purpose, gait data of several elderly individuals is collected many times over a period of time using Kinect sensor. The acquired data consist of RGB image sequences and depth data. From this data, 3D pose of the individual is identified. These 3D poses are used to extract the necessary gait parameters of the individual. The extracted gait parameters will be used in future to assess the health condition of the individual.

SHM is restricted to the variable region, whereas, CSR is confined to the constant region of immunoglobulin (Ig) genes. Activation-induced cytidine deaminase (AID) is a crucial player in the diversification of antibodies in the activated B-cell. AID catalyzes the deamination of cytidine (C) into uracil (U) at Ig genes. Subsequently, low fidelity repair of U:G mismatches may lead to mutations. Transcription is essential for the AID action, as it provides a transient single-strand DNA substrate. Since splicing is a co-transcriptional event, various splicing factors or regulators influence the transcription. Numerous splicing factors are known to regulate the AID targeting, function, Ig transcription, and AID splicing, which eventually influence antibody diversification processes. Splicing regulator SRSF1-3, a splicing isoform of serine arginine-rich splicing factor (SRSF1), and CTNNBL1, a spliceosome interacting factor, interact with AID and play a critical role in SHM. Likewise, a splicing regulator polypyrimidine tract binding protein-2 (PTBP2) and the debranching enzyme (DBR1) debranches primary switch transcripts which later forms G-quadruplex structures, and the S region guide RNAs direct AID to S region DNA. Moreover, AID shows several alternate splicing isoforms, like AID devoid of exon-4 (AIDΔE4) that is expressed in various pathological conditions. Interestingly, RBM5, a splicing regulator, is responsible for the skipping of AID exon 4. In this review, we discuss the role and significance of splicing factors in the AID mediated antibody diversification.

Using different image and video processing applications, these image data are manipulated, and thus, original images get tampered. These tampered images are the prime source of spreading fake news, defaming the personalities and in some cases (when used as evidence) misleading the law bodies. Hence before relying totally on the image data, the authenticity of the image must be verified. Works of the literature are reported for the verification of the authenticity of an image based on noise inconsistency. However, these works suffer from limitations of confusion between edges and noise, post-processing operation for localization and need of prior knowledge about an image. To handle these limitations, a noise inconsistency-based technique has been presented here to detect and localize a false region in an image. This work consists of three major steps of pre-processing, noise estimation and post-processing. For the experimental purpose two, publicly available datasets are used. The result is discussed in terms of precision, recall, accuracy and f1-score on the pixel level. The result of the presented work is also compared with the recent state-of-the-art techniques. The average accuracy of the proposed work on datasets is 91.70%, which is highest among state-of-the-art techniques.
