Objectives The project in this semester is an interdisciplinary project. It combines distributed systems design, computer science and computer networks. PDA based flexible ticket system You are going to implement a prototype of a flexible ticket system. In its complete version it is going to replace the current RF-id tag based system. The new system expected lifetime is 5 year only. In 5 years it is expected that face recognition has advanced sufficiently to allow ticketing based entirely on automatic unattended image processing. While the proposed system only partly reduces the manual control, it will reduce the amount of sign in /sign out equipment on platforms and placing that equipment entirely in the rolling stock. Each train compartment or bus is already equipped...

My Windows Server 2022 has suddenly stopped accepting Remote Desktop sessions. Each time I try, the client shows a generic “network error” and never reaches the credential prompt. The network interface, firewall rules, and port forwarding all look correct on my side, so the usual checks haven’t revealed anything obvious. I need someone who can step in, locate the real cause of the connection failure, and restore a stable RDP service without disrupting the other roles running on the server. You are free to use any standard tools you rely on—Event Viewer, PowerShell, Network Monitor, Group Policy review, or NIC/drivers diagnostics—as long as the end result is a working, secure Remote Desktop connection. Deliverables • Root-cause report des...
...and I want a fellow Serbian-based specialist who can keep it healthy while moving it forward.

Once these pieces are live, I’ll rely on you fo...

I’m searching for production-ready AI agents I can roll out across several verticals—specifically Healthcare, Real Estate, E-commerce, Blockchain, Crypto, and Social Media. Each solution must already be live somewhere so I can see it operating in real time before we move forward. The core requirements are straightforward: the agent needs to run in a browser, accept its own knowledge base or document set for context, and ship with source code plus clear documentation. I’m also expecting help getting the code stood up in a SaaS or on-prem environment. I’m flexible on architecture; whether you built it around OpenAI, Claude, Llama, FastAPI, Node.js, Pinecone, FAISS, or Weaviate doesn’t matter as long as it performs reliably at scale. ...
