Investigation of white layer thickness, material removal rate, and tool wear rate of Inconel 718 by nano-Al2O3-mixed electrical discharge machining [PDF]

Engineering and Technology Journal
Nano powder mixed electrical discharge machining (NPMEDM) is an advanced thermo-physical process. It is used to create complex, precise shapes in hard-to-machine materials, such as nickel-based alloys like Inconel 718, due to their mechanical properties.

Impact of Irrigation Scheduling on Corn Yield and Water Balance in Sandy Soils of Central Minnesota Using the EPIC Model.

Irrigation and Drainage, EarlyView.
ABSTRACT Efficient irrigation scheduling is critical in sandy soils to achieve optimum yield and maximum net benefit with minimum environmental concerns. The Environmental Policy Integrated Climate (EPIC) model was used to study the impacts of autoirrigation of corn on crop yield and soil water balance during 2019–2021 at −300 and −450 kPa for loamy ...

Twenty‐four month clinical outcomes of modified coronally advanced tunnel technique with leukocyte‐ and platelet‐rich fibrin–functionalized porcine dermal matrix for single/multiple gingival recessions

Journal of Periodontology, EarlyView.
Abstract Background To report 24‐month clinical and 3D outcomes of single and multiple RT1 and RT2 gingival recessions treated with the modified coronally advanced tunnel (MCAT) technique and an L‐PRF‐functionalized porcine dermal matrix (PDM), as long‐term data on PDM in root coverage are scarce.

Safety and efficacy of weekly adalimumab 80 mg therapy in pediatric Crohn's disease

Journal of Pediatric Gastroenterology and Nutrition, EarlyView.
Abstract Objectives Adalimumab is commonly used to induce and maintain remission in pediatric Crohn's disease (CD). However, data on the efficacy and safety of high‐dose adalimumab in this population are limited. This study aimed to evaluate the therapeutic effectiveness and safety of weekly high‐dose adalimumab (80 mg) in pediatric CD patients ...

Multiobjective optimization of EDM machining parameters of TIB2 ceramic materials using regression and gray relational analysis

High Temperature Materials and Processes
The aerospace industry widely uses titanium diboride, a tough material that is challenging to machine using conventional methods. We, therefore, process titanium diboride (TiB₂) to determine the best process parameters for electrical discharge machining ...

3D Surface Profiling via Direct End‐to‐End Regression With a Photonic Geometric Sensor

Laser &Photonics Reviews, EarlyView.
Measurements of microscale surface patterns are essential for quality control across semiconductor and biomedical industries, yet the development of miniaturized, intelligent systems remains constrained by the complexity and bulkiness of conventional benchtop metrology.

CONCERT: A Modular Reconfigurable Robot for Construction

Journal of Field Robotics, EarlyView.
ABSTRACT This paper presents CONCERT, a fully reconfigurable modular collaborative robot (cobot) for multiple on‐site operations in a construction site. CONCERT has been designed to support human activities in construction sites by leveraging two main characteristics: high‐power density motors and modularity. In this way, the robot is able to perform a

Probability density function of turbulence fading in MRR free space optical link and its applications in MRR free space optical communications

IET Communications, 2017
Probability density function (PDF) of the modulating retro‐reflector (MRR) turbulence fading channels is crucial for the performance analysis of MRR communication systems. In this study, closed‐form expression for the PDF of normalised MRR free‐space optical (FSO) turbulence fading coefficient is obtained first.
