Am nevoie de un concept complet de design pentru un site web modern care să includă o secțiune de blog ușor de administrat. Caut un look curat...de stil (paletă de culori, iconografie, fonturi) care să păstreze un aer modern. • Layout dedicat pentru blog: listă articole, pagină detaliu, elemente de navigare și call-to-action. • Ghid rapid de implementare (specificații spacing, dimensiuni, stări hover) pentru a facilita hand-off-ul. Accept mock-up-uri iterative; voi oferi feedback rapid pentru ajustări. Dacă ai experiență cu design systems sau Atomic Design, menționează acest lucru—mi-ar plăcea să avem o bază scalabilă pentru viitoare extensii.

...creating a secure and stable "inside-out" virtual network. Project Description We have multiple locations with mobile surveillance systems equipped with Hikvision cameras. Each system is connected to the internet via two providers (DIGI and Vodafone) that use CGNAT with private IP addresses. This setup prevents direct external access to the cameras and, consequently, their connection to a central NVR. We aim to implement a VPN solution that creates a secure tunnel from each location to a central VPN server (VPS), allowing the central NVR to access the remote cameras as if they were on the same local network. The routers used in all mobile surveillance systems are Teltonika RUT901. Project Objectives Configure and secure a VPN server (preferably WireGuard or Ope...

This paper aims to evaluate the performance obtained by the V-BLAST detection algorithm in MIMO (Multiple-Input Multiple-Output) systems. The simulations will be performed by writing lines of code in the Matlab simulation environment. Consider a MIMO system in a configuration with 2 transmitting antennas and 2 receiving antennas (2x2) MIMO) when a random string of bits will be transmitted, with and without the V-BLAST detection algorithm implemented. The performance of the proposed system will be tested through scenarios in which the number of active users at a given time in the network will vary, different modulation techniques will be used (BPSK, QPSK) when the channel is affected by different types of fading (Rayleigh, Rice ) and Code Division Multiple Access (CDMA) using real sp...

Buna ziua,  Va contactez din partea firmei Network Systems. Firma noastra se ocupa de verificarea magazinelor online care folosesc baza de date tecdoc. Am aflat ca ati lansat un proiect pentru a implementa baza de date piese auto intr-un magazin online.  As dori sa va atrag atentia, ca folosirea datelor Tecdoc este permis numai dupa achizitionarea  licentei Tecdoc.

I have a clean, manifold pilot model saved in 3ds Max 2024 and need a straightforward skeletal rig applied. No facial controls or muscle systems are required—just a solid biped/CAT setup that bends naturally at the major joints. Once the rig is in place, save out two distinct poses for me: • seated naturally in a cockpit, hands on the controls (see pics for reference) • standing, relaxed, leaning casually against the aircraft fuselage (see pic for reference) Please keep everything inside the same 2024 Max environment so I can drop the file straight into my existing scene. Acceptance is simple: joints rotate without odd collapses, extremities stay proportional in both poses, and the skin holds volume when elbows and knees bend. It's critical that the mat...

I need a small, self-contained module that talks to the KLing 2.6 Pro API, takes the image set captured by my Breeze Systems photobooth software, and stitches those frames into a short mp4. The first captured image must appear as a still for a configurable number of seconds, the remaining shots play through in sequence, and the last frame freezes for an outro of equal length. Audio is not required; smooth cross-fade or simple cut transitions are fine as long as there is no visible stutter. The workflow I have in mind: • Breeze Systems saves the JPEG set into its usual session folder. • Your component is triggered (command-line call or REST endpoint—whichever is easiest to bolt on). • It calls KLing 2.6 Pro to do the heavy lifting, respecting the tim...
