The operator would keep the telescopic gunsight centred on the target, and the automated systems would guide the missile to that point using radio commands. The optical system ensured high accuracyso it was developed with the intent of directly hitting its target, reducing the size of the warhead required to guarantee a kill, and eliminating the need for a proximity fuse. BAC joked that the system was a "hit-ile", as opposed to a "miss-ile". That eventuality came to pass, and ET.
Bellovin, Jason Nieh Email privacy is of crucial importance. Existing email encryption approaches are comprehensive but seldom used due to their complexity and inconvenience. We take a new approach to simplify email encryption and improve its usability by implementing receiver-controlled encryption: To avoid the problem of users having to move a single private key between devices, we implement per-device key pairs: Compromising an email account or email server only provides access to encrypted emails.
Mail, has acceptable overhead, and that users consider it intuitive and easy to use. On the one hand, some people claim it can be accomplished safely; others dispute that.
In an attempt to make progress, a National Academies study committee propounded a framework to use when analyzing proposed solutions. Robot Learning in Simulation for Grasping and Manipulation Beatrice Liang Teaching a robot to acquire complex motor skills in complicated environments is one of the most ambitious problems facing roboticists today.
Grasp planning is a subset of this problem which can be solved through complex geometric and physical analysis or computationally expensive data driven analysis. As grasping problems become more difficult, building analytical models becomes challenging.
Consequently, we aim to learn a grasping policy through a simulation-based data driven approach. POS uses a novel priority-based scheduling algorithm that naturally considers partial order information dynamically, and guarantees that each partial order will be explored with significant probability.
This probabilistic guarantee of error detection is exponentially better than state-of-the-art sampling approaches. Besides theoretical guarantees, POS is extremely simple and lightweight to implement.
In our design, an elastic lens array is placed on top of a sparse, rigid array of pixels. This lens array is then stretched using a small mechanical motion in order to change the field of view of the system. We present in this paper the characterization of such a system and simulations which demonstrate the capabilities of stretchcam.
We follow this with the presentation of images captured from a prototype device of the proposed design. Our prototype system is able to achieve 1. To manage an IoT device, the user first needs to join it to an existing network.
Then, the IoT device has to be authenticated by the user. The authentication process often requires a two-way communication between the new device and a trusted entity, which is typically a hand- held device owned by the user.
To ease and standardize this process, we present the Device Enrollment Protocol DEP as a solution to the enrollment problem described above. The application allows the user to authenticate IoT devices and join them to an existing protected network.
However, RNNs are still often used as a black box with limited understanding of the hidden representation that they learn.
Existing approaches such as visualization are limited by the manual effort to examine the visualizations and require considerable expertise, while neural attention models change, rather than interpret, the model.
We propose a technique to search for neurons based on existing interpretable models, features, or programs. Reliable Synchronization in Multithreaded Servers Rui Gu State machine replication SMR leverages distributed consensus protocols such as PAXOS to keep multiple replicas of a program consistent in face of replica failures or network partitions.
This fault tolerance is enticing on implementing a principled SMR system that replicates general programs, especially server programs that demand high availability.
Unfortunately, SMR assumes deterministic execution, but most server programs are multithreaded and thus non-deterministic. Moreover, existing SMR systems provide narrow state machine interfaces to suit specific programs, and it can be quite strenuous and error-prone to orchestrate a general program into these interfaces This paper presents CRANE, an SMR system that trans- parently replicates general server programs.
It leverages deterministic multithreading specifically, our prior system PARROT to make multithreaded replicas deterministic. It uses a new technique we call time bubbling to efficiently tackle a difficult challenge of non-deterministic network input timing.

Partial Interleaved Drift Correction. Due to its design of using two lasers per base station that sweep the tracking volume alternatingly left-to-right and bottom-to-top, Lighthouse adds an extra wrinkle to drift correction (see Figure 5).
Passive radar systems (also referred to as passive coherent location and passive covert radar) encompass a class of radar systems that detect and track objects by processing reflections from non-cooperative sources of illumination in the environment, such as commercial broadcast and communications signals.
